Vampire and Werewolf romance may have owned the big screen this year, but off screen celebrity match-ups were especially wishy-washy with quite a few "are they or aren't they" relationships.

And Hollywood's notorious short term loves moved over for the meltdowns of long-term romances. Forget the amicable breakups a-la Jennifer Aniston and Vince Vaughan or Bruce Willis and Demi Moore. Insults and slights reigned supreme in this year's breakups.

Here's a rundown of the hottest breakups and hookups Hollywood had on offer this year.

Tiger Woods and Elin Nordegren

  • Status: Questionable

You know this tale. A mysterious SUV crash and all the controversy surrounding it, including proclamations by over a dozen women that they had affairs with the world's No.1 golfer. After weeks of speculation, Tiger finally admitted to "infidelity" in December. He and Nordegren are reportedly renegotiating their prenuptial agreement, and the two are seemingly desperate to work out their marriage for the sake of their two young kids. This story keeps changing every day, so it's hard to make predictions on what is to come for the couple.

Kristen Stewart and Robert Pattinson

  • Status: Questionable

Sure, the human and vampiric Twilight lovers hook up on screen, but are they together in real life, or aren't they? The tabloids say yes and photos show them snuggling in a movie theatre...or are they just leaning in to talk so they can whisper and not get kicked out? Tabloids put these two all over the place, from reporting that they definitely are not together, to rumours that they are engaged. At the screening for the latest Twilight movie "New Moon," the two kept their distance. Does life imitate art? Or is this one a publicity stunt to keep the two in the spotlight while their movie brings in cash at the box office? We might have to wait until all the Twilight movies are out before we'll know for sure.

Rihanna and Chris Brown

  • Status: Broken up

What a mess. No one won in this sad tale of domestic violence. By now you know every detail of the saga. On their way to the Grammy awards, Brown beat Rihanna after an argument they had in the car. Leaked photos of Rihanna showed her battered and bruised. Brown plead guilty to assaulting her, and was sentenced to probation and community service. Rihanna recently sold 181,000 copies of her new album in its first week. Brown, who was an up-and-coming star with his smash hit "Forever" will have to wait a little longer to see if the public forgives him or whether he's lost his momentum for good. We'll find out how well he fares when his album is released later this month.

Jessica Simpson and Tony Romo

  • Status: Broken up

It can't get much worse than this. After being verbally attacked for those unflattering mom jeans, unlucky-in-love songstress Jessica Simpson got dumped by longtime BF and Dallas Cowboys quarterback Tony Romo...on the day before her birthday!

But Jessica will certainly have the last laugh here. Her successful hair extension, cosmetic and purse lines are raking in big cash. Her final kick in Romo's teeth is a new TV show, which looks at perceptions of beauty in different countries around the world. And who outside the sports realm had ever heard of Tony Romo before he and Simpson became an item? And who has heard of him since?

Justin Timberlake and Jessica Biel

  • Status: Questionable

The troubles of this private couple went public in the fall when the two reportedly broke up. Photos of the two together in Vancouver in October suggest they are back on. But for how long? Reports say Biel, who is filming "The A-Team" with Bradley Cooper in Vancity, can stick around as long as she stops pushing JT for marriage. Ouch.

Steven Page and the Barenaked Ladies

  • Status: Broken up

Sure the band itself didn't break up, but it was pretty hard to imagine BNL without front man of 20+ years Steven Page. Page left the band in February to pursue solo projects after some troubled years in his personal life, including a divorce and cocaine charges sullying his clean-cut image. Page's solo album is expected to be released sometime in 2010. Meanwhile the Ladies will perform one of the biggest gigs of their lives at the Olympics and say they will go on without him. Their newest album -- sans Page -- was scheduled to be released sometime this fall, but hasn't dropped yet.

Jon and Kate Gosselin

  • Status: Broken up

This couple has a reality show to thank for rocketing them and their eight kids to stardom...and their divorce proceedings. Their angry faces constantly glaring back at you from those supermarket tabloids might have you thinking more along the lines of "Jon and Hate." Did he steal her money? Did he cheat? One thing is for sure, their TV show went off the air permanently in November after a string of ugly lawsuits with TV network TLC, and when someone got child labour investigators involved. These two, along with Kate's odd haircut will likely soon fall off the celebrity gossip radar...but not if Jon or Kate have anything to say about it. Word has it Jon is pushing his own reality show, which no one seems to want, and Kate is trying to sell eco-friendly toys and makeup.

Avril Lavigne and Derryck Whibley

  • Status: Broken up

She was only 21 when she married Whibley, front man for punk-rock band Sum 41, and their marriage went the way of many celebrity romances: Splitsville. Fans of Sum 41, who likened Lavigne to a band-killing Yoko Ono rejoiced. Sum 41 has not produced any significant music since Whibley's marriage.

It took these two no time to move on. Just a few weeks after the divorce went public, Whibley was seen getting twin tattoos of a safety pin with model Hanna Beth Merjos, and Lavigne was spotted hitting an L.A. club with former "That 70s Show" foreign exchange student Wilmer Valderrama.

Mel Gibson and Robyn Gibson

  • Status: Broken up

Twenty-eight years of presumable wedded bliss went down the tubes for superstar Mel Gibson. His wife and the mother of seven of his children filed for divorce in April citing "irreconcilable differences." These differences might also be called Oksana Grigorieva, a Russian model who gave birth to Mel Gibson's eighth child, a girl, in October. Gibson seems to be duking it out with Nadia Suleman, the infamous Octomom for alpha-fertile status. On an appearance on the Tonight Show, he dubbed himself Octo-Mel.

Taylor Lautner and Taylor Swift

  • Status: Questionable

This one gets the award for most confusing hookup of the year. The Taylors, who are co-starring in the upcoming movie "Valentine's Day" have allegedly brewed up some romance off screen, being spotted at a hockey game in L.A. The teen country songstress, who has swept awards shows this year, sang praises for her single life in an interview with In-Style magazine in November, yet both play coy about their relationship. The most solid information that could prove this one is on is Lautner's December appearance on Saturday Night Live. He kicked some cardboard Kanye West butt for infamously interrupting Swift's acceptance speech at the MTV Video Music Awards.

Sean Penn and Robin Wright (Penn)

  • Status: Questionable

Will these two make up their minds? They've filed divorce papers TWICE in their 13 year marriage. Just last year, the two withdrew their divorce papers from a California court. But then Sean Penn filed again...only to withdraw his papers AGAIN in May, saying he made "an arrogant mistake." But then...you guessed it, Robin Wright Penn filed divorce papers in August, citing "irreconcilable differences." At least the two seem to agree on one thing--shared custody of their 16 year old son, Hopper.

LeAnn Rimes and Eddie Cibrian

  • Status: Confirmed

Newly minted CSI: Miami star Cibrian and Rimes met on the set of their upcoming TV movie "Northern Lights." They were first caught on camera canoodling at a Vegas nightclub. Soon after, both stars announced divorces from their spouses. Cibrian's wife has been especially scorned, changing her tune from defending him earlier in the year to publicly saying that the two "deserve" each other. Cibrian and Rimes were caught on camera soon after vacationing together in Mexico. This one took a turn for the recently, when court documents surfaced that showed Cibrian alleging his wife physically attacked him and vandalized his motorcycle once their marriage fizzled.
