Christina Milian has lost seven pounds over the past week.

The 'Dancing With The Stars' contestant, who is engaged to the CEO of Rap-A-Lot Records, Jas Prince, has revealed she is already seeing results from her intensive training schedule in Los Angeles and is thrilled with her slimmer figure.

The 31-year-old singer, who has a three-year-old daughter, Violet, with her ex-husband The Dream, tweeted a picture of her trim torso and legs on Saturday (21.09.13), adding: ''I've already lost 7lbs since I started #dwts! Owww!''

Kelly Osbourne previously credited the dancing competition for helping her to kick-start a lifestyle overhaul, which has led to her losing over 60 lbs. since she appeared on the show in 2009.

Kirstie Alley also claimed she lost 100 pounds after appearing on the show in 2011.

The 62-year-old star said: ''I feel like I'm back in my element. I honestly didn't even realise what I looked like.

''Before 'Dancing with the Stars,' I bought these dresses from size 14 to 4. [They were] all the same dress, and I said, 'You know what I really want? I really wanna be in this dress in a 4!'''
