LeAnn Rimes' Scary Slimdown

LeAnn Rimes' scary skinny physique didn't happen overnight.

In 1996, Rimes was a fresh-faced, average-sized thirteen year old girl, taking the country scene by storm for the first time. By the time she married backup dancer Dean Sheremet in 2002, she was petite but still healthy for her big day. 

But when Rimes fell in love with her TV-movie costar Eddie Cibrian (they were both married at the time, but went public with their romance in fall 2009), her weight began to dwindle.

Around the time of Rimes' engagement in January 2011, Us broke the news that the country star got a boob job -- and she even used Cibrian's ex-wife Brandi Glanville's plastic surgeon and got the same cup size!

In May, Rimes tweeted an extremely thin photo of herself in a bikini, then defended her tiny frame. "This is my body, and I can promise you I'm a healthy girl," she said. "I'm just lean. Thanks for your concern, but no need to be."
