Bar Refaeli breaks her arm

Bar Refaeli has revealed on twitter that she has broken her arm.

The supermodel - who is the ex-girlfriend of Leonardo DiCaprio - has been left with the nasty injury after an unknown accident and she is not happy about it.

She wrote on her twitter page: "I broke my arm. And I'm annoyed! Booooooo. (sic)"

No other details about how she got the injury are known yet.

Bar's followers on the micro-blogging website were quick to send her get well soon messages.

User AzulinR tweeted: "Oh yikes!! Sorry to hear that, yaldonet! Hope it heals very very quickly!! (sic)"

One cheeky fan even offered to help the stunning Sports Illustrated swimsuit model get dressed while she is incapacitated.

Her follower AustinMichael wrote: "If you need some help putting your bikini on, let me know ... lol. (sic)"

Bar and Leonardo separated in May after being in a relationship on and off for over five years.

They decided to call time on the romance because they had "grown apart" and were both focused on their careers.

Since the break-up, the 36-year-old actor has started dating 'Gossip Girl' star Blake Lively, 23.

Bar, 26, has not been romantically linked with anyone since the relationship ended.

Chace Crawford & Bar Refaeli Couple Up

Chace Crawford and Bar Refaeli are starting to get friendly with each other.

The Gossip Girl hunk and Sports Illustrated cover model, both 24, shared a special moment on Friday night (September 11) at NYC hotspot 1Oak.

During Jay-Z’s “Run This Town,” they were “dancing on each other, swaying their hips together from side to side,” a partygoer exclusively tells JustJared.com. “At one point, Bar reached down and grabbed Chace’s backside. They were very affectionate with each other.”

Another source reveals, “Bar and Chace have been spending a lot of time together since Bar is town and attending NY Fashion Week events.” (During Fashion’s Night Out on Thursday, Chace dropped by the Dolce & Gabbana boutique while Bar was at the Ralph Lauren boutique.)

Spotted at the booth next to the unlikely pair: Rihanna hanging out with her entourage. Jay-Z and Kanye also dropped by the club, celebrating their performance together from earlier in the evening at Jay-Z’s 9/11 benefit concert.

Last month, Chace was seen kissing Twilight cutie Ashley Greene. Bar called it quits with Leonardo DiCaprio back in June and has been linked to Brazilian polo player and entrepreneur Ricardo Mansur.
