She's always been known as one of the more curvier members of Girls Aloud.
But it looks like Kimberley Stewart is looking less of the woman she used to be thanks to the 'West End diet'.
Treading the boards eight shows a week playing Princess Fiona in Shrek: The Musical, the 30-year-old singer has been shifting the pounds.

With her theatre schedule taking up most of her time, Walsh is rarely out on the London social scene these days.
So when she arrived at the ITV studios to appear on Loose Women today, it was one of the first times fans were able to see her new figure.
The singer looked casually chic in a pair of skinny jeans, black jumper and Christian Louboutin peep-toe heels.

Talking to the Loose Women before dashing to the Theatre Royal Drury Lane for a matinee performance, Walsh admitted the shows were gruelling.
She said: 'It's really hard work, but its really good fun. It's eight shows a week. Its full on.'
Having started out in acting as a child before turning her attention to singing, Walsh admitted she's having fun going back to her theatre roots.
She enthused': 'It felt like going back to my roots because I grew up doing musical theatre. I missed it.'
And despite having an American accent in Shrek, in real-life the Bradford-native still has her Yorkshire accent.
She admitted: 'It has softened slightly over the years after getting sick of people going, "Sorry, what did you say?"
Walsh also admitted she had started talking to her Girls Aloud bandmates Sarah Harding, Nadine Coyle, Cheryl Cole and Nicola Roberts about a potential reunion for their 10th anniversary.
She said: 'We're gonna do something very special. we're chatting at the moment. I can't divulge anything. It's gonna be more than a one-off, but we don't know to which extent...'
