Rail thin: Sophie Monk looked incredibly gaunt at the premiere of The Sorcerer's Apprentice in Los Angeles last night and right, in 2008
It seems heartache has taken a serious toll on Australian actress Sophie Monk.
The 30-year-old, who recently found her ex-boyfriend in bed with another woman, revealed a startlingly thin frame as she attended the LA premiere of The Sorcerer's Apprentice last night.
Not even her freshly dyed brown hair - which has always been bombshell blonde - was enough to distract from her rail thin shape.
The former singer moved to the US a few years ago to carve out a Hollywood career, landing small parts in films such as Click and Date Movie.
Ex factor: Sophie with her former boyfriend, plastic surgeon John Diaz
But she has become more famous for her romances, having dated Good Charlotte rocker Benji Madden prior to his relationship with Paris Hilton.
Her most recent liaison has proved to be the most dramatic yet.
Sophie recently split from her plastic surgeon boyfriend John Diaz after she caught him cheating on her.
She said during an interview with an Australian radio station last week: 'I rock up in the morning with a coffee and presents and he [Diaz] had a present there - a chick.”
She initially fled the scene, before deciding to confront him.
'I walked back in and went, "What’s going on?" and actually had a conversation,' she recalls. 'I spoke to the girl. She was in shock. I didn’t know her. She was innocent.'
Sophie recently wrapped filming The Legend of Awesomest Maximus, a comedy starring actor Rip Torn and former Beverly Hills 90210 star Ian Ziering.
