Muscular: Renee Zellweger proudly showed off her bony back at the Metropolitan Museum of Art Costume Institute gala in New York last nightShe has famously battled with her weight after piling on the pounds to play Bridget Jones.
But it seems Renee Zellweger is finally happy with her figure, judging by pictures of her at the Metropolitan Museum of Art Costume Institute gala in New York last night.
The 42-year-old actress showed off her super-slim frame in a backless gold Carolina Herrera gown as she attended the prestigious fashion event.
However, perhaps Renee didn't check her back view in the mirror before she walked the red carpet, as the sheer dress drew attention to her incredibly bony, muscular back.
Daring: Renee's pretty gold Carolina Herrera gown featured a V-back and drew attention to Renee's slim physiqueHer shoulder blades looked very prominent in the gown - a sure sign Renee has been working hard in the gym to hone her muscular physique.
But newly-single Renee looked thrilled with the outfit, posing so photographers could snap ever angle of the shimmering dress.
And, to ensure the backless gown was displayed to its full potential, Renee even wore her hair in an up 'do so the back view wasn't obscured in any way.
Every angle: Renee even wore her hair up so all attention was focused on her bony backThe Cold Mountain actress is no stranger to attracting criticism for her weight, after taking the weight loss too far following her portrayal of singleton Bridget Jones.
Renee was famously paid a bonus sum on top of her £9.5 million (USD$15m) paycheck for every pound she gained for the movie's sequel Bridget Jones: The Edge of Reason in 2004.
The actress is said to have gained 20 pounds for the 2001 original and 30 pounds for the sequel.

Careful! The long train on Renee's dress could have proved problematic as she made her way up the stairs
Leggy: The actress took care with the delicate train as she arrived in a car at the after-partyBut, after finishing the movies, Renee hit the gym with a vengeance to shed the weight, and has continued to work out virtually every day to maintain her slim figure.
While there was talk recently of the possibility of a third Bridget Jones film being made, it was reported Renee is thinking of wearing a fat suit if she takes on the role again because she is too concerned about the health implications of her yo-yo dieting.Talking recently about how her body has been affected by her ever-changing weight, Renee said: 'Can I just tell you my body is whacked by the time we finish one of those!
'It doesn't know what has happened because it thinks there's supposed to be a baby and there's no christening.'
'Did you see that movie about fast food, Supersize Me?
'I had a panic attack with all the specialists talking about how bad this is for you, long term, putting on that much weight in short periods of time.
'And they're all saying, "You must stop this now or you're going to die".'
Despite her unusual choice of dress for last night's event, Renee appeared in good spirits and smiled widely for photographers as she posed on the red carpet.
However, Renee's happy facade may have slipped when she stepped inside and found that her ex-boyfriend Bradley Cooper was also in attendance.
The couple split in March after nearly two years together, apparently because Cooper wanted to concentrate on his career rather than a relationship.
But Renee can take comfort in the fact that Cooper didn't choose to take a date to the Met gala last night, instead opting to invite his mother Gloria to accompany him.

Shortly after the couple's split in March, a friend of the actor said it was Cooper's professional ambition which led to their break-up.
The friend said: 'If I had to pick any possible mistress it would be Brad's career. He worked really hard to get into leading man status.'
