Kim Kardashian has accused Adrienne Bailon of kicking Rob Kardashian "when he's down."

The 33-year-old reality TV star has hit out at her brother's ex-girlfriend following her recent claims that dating the sock designer hurt her career.

The actress-and-singer - who dated Rob from 2007 to 2009 - suggested that appearing on the family's reality show 'Keeping Up with the Kardashians' did her career more harm than good in an interview with Latina magazine.

A furious Kim wrote on Twitter in the early hours of Wednesday morning.

 

"So sad when people try to kick my brother when he is down #FamilyForever (sic)"

Kim took a further dig at the 30-year-old star by referring to the song 'Let It Go', which appears on the soundtrack to hit Disney film 'Frozen'.

She wrote: "#LetItGoooooLetItGoooooo (FROZEN VOICE) (sic)"

Adrienne, who claims Rob cheated on her during their two-year relationship, expressed her regrets over appearing on the Kardashians' E! reality show, saying: "To be stuck with that Kardashian label, that was so hurtful to me and to my career. I probably realised that too late - not that it would've affected my decisions in terms of who I dated, but it would've affected my decision to appear on the show."

Kim's defence of Rob - who never attended his sister's recent wedding to Kanye West and reportedly hasn't spoken to her since - comes as the 27-year-old star continues to battle weight problems which have plunged him into depression.

The brunette beauty has taken a firm approach with her sibling, insisting it's up to him to change his lifestyle.

She said: "I think I'm just more of the tough love kind of person. My personality is like, 'All right, you complain, you don't like it, get up and do something about it.' "

David Beckham's plans to bring a Major League Soccer team to Miami are in jeopardy as he has yet to find a suitable location for the stadium.

The 39-year-old soccer star quit the professional sport in 2013 following a successful 20-year career and wants to create his own team in Florida but MLS commissioner Don Garber has warned that league will not approve a team until a stadium is secured.

He told ESPN: "Miami remains a top priority for us. But we are mindful of the challenges we had in the past and must have the right ownership group and stadium location. David has been working to secure additional partners, all, if approved, would be terrific MLS owners. David and his partners have not yet been able to secure a site that we believe provides the proper access and iconic presence that will help ensure success."

And he insisted that it must be a downtown location or else David's franchise bid will be quashed.

He added: "We remain focused on a downtown Miami location, and we will not expand to Miami unless we have a downtown site for the stadium."

David had considered a plot near the American Airlines arena on Biscayne Blvd, Miami, where basketball side Miami Heat play their home games, but the city did not give approval for the site.
