She's only a week into the competition, but Dancing With the Stars
contestant Christina Milian
is already feeling the effects of those daily dance rehearsals – she's losing weight.
"I've already lost 7lbs since I started #dwts! Owww!" she Tweeted
on Saturday, along with a pic of herself in David Lerner leggings that showcased her slimmer legs and torso.
Milian, 31, isn't the first star who's lost weight after joining the reality show – Kelly Osbourne
shed 20 lbs., Marie Osmond dropped
31 lbs. before going on to lose 16 more after the competition ended, Chaz Bono kick-started a 65-lb. weight loss
on the show, and Kirstie Alley
claimed that she lost a staggering 100 lbs.
But not all the celebrities who competed on the show have been happy about their sudden slim-downs – Jane Seymour told PEOPLE
in 2007 that she was trying to put some weight back on after shedding 20 lbs. from her rigorous dance training.
