TORONTO -- Not even Celine Dion can out-diva Miss Piggy -- or apparently out-sing her, according to the prima donna porker.

Miss Piggy held court in Toronto on Tuesday to promote the new film "Muppets Most Wanted," in which she sings a song with Dion.

Asked who was the bigger diva on set, the siren of the swine world didn't hold back.

"Well, naturally moi," she said in an interview, wearing her signature pearls, white gloves and a low-cut black-and-white patterned wraparound dress (asked who she was wearing, she quipped: "Well, I don't want to say it's a knockoff of a Diane Von Furstenberg.")

"I actually have a 'No Competing Diva' clause in my contract, so that was taken care of before she even arrived on set."

The Quebec chanteuse was "wonderful" to work with, added Miss Piggy, noting the two are "very dear friends" and "spoke lots of le French" together on the set of the musical comedy.

But apparently Dion did have some trouble with their piano ballad, "Something So Right."

"I invited her to guest artist on a little solo that I have in this movie and I thought she did very well," said the karate-chopping leading lady.

"I only had to go into the studio and fix a couple of her notes, the really high ones. She has trouble with those."

Never one for humility, Miss Piggy said she thinks her own performance on the song is "pretty good."

And if the tune gets an Oscar nomination, as some have speculated?

Well, Miss Piggy said Dion can "come up onstage" with her.

"But I'm the one taking home that golden boy, OK! Me!" add the feisty blond bombshell, batting her thick eyelashes.

Disney's "Muppets Most Wanted" sees the naive gang going on a global tour led by a conman played by Ricky Gervais and a Russian criminal pretending to be Kermit, who is wrongfully imprisoned in Siberia.

Co-stars include Ty Burrell as an Interpol agent and Tina Fey as a prison guard.

"Flight of the Conchords" co-creator James Bobin, who directed Disney's "The Muppets" from 2011, also helms this version and wrote the screenplay with Nicholas Stoller.

The film features a slew of cameos from stars including Danny Trejo, Tom Hiddleston and Salma Hayek.

Miss Piggy spends much of the film trying to convince longtime beau Kermit to get married -- something she insists will happen one day.

"Don't ask when, because I don't have that answer," she said at a posh downtown hotel. "But yes, sometime in the future it will happen. I'm sure of it."

The gluttonous glam queen has often said she'd like to wed Kermit in France, but concedes: "It's really hard for Kermit to go to France. It's the whole frog legs thing."

Would she consider tying the knot in another French-speaking region -- Quebec -- instead?

"Maybe, maybe. Or maybe the Paris Hotel in Las Vegas."
