After going up five dress sizes during her pregnancy with son Bobby, Jennifer Ellison described herself as a 'hippo mama'.
But after losing five stone and regaining her pre-baby size 8 figure, the former Brookside actress has been proudly showing off the results.
And there's no surprise the star will be sharing her weight loss secrets in an upcoming fitness DVD.

Alongside the caption: 'Shooting my fitness DVD commercial! Here's a sneaky pic!', the mother-of-one looked super svelte and toned in a sports bra and hotpants.
The latest image shows the Hell's Kitchen winner look even slimmer than her official DVD cover shoot, which she posted online just two weeks ago.

Jennifer Ellison's Fat Blaster Workout goes on sale on December 26When she uploaded it last month, she revealed she had lost another stone - taking her to a total weightloss of five stone since giving birth to son Bobby in February 2010.
She enthused: 'Hey guys!! I've lost another stone! Here's a totally untouched pic from my new fitness DVD available to pre-order now.'
The 5ft 7 star admitting ballooning from a size 8 to 18 during her pregnancy and said she struggled to lose the weight afterwards.
She lost some weight last year after enrolling at boot camp in preparation for her nude scenes in the touring production of Calendar Girls.
Reflecting on her weight gain, she said: 'I got huge. I looked like a hippo.
'I had absolutely no idea how I had ballooned during my pregnancy. All I thought about was eating plenty of food to keep my baby healthy.
'I was pregnant at the same time as Coleen Rooney and Denise Van Outen. Denise seemed to snap straight back into her normal clothes and I remember looking at Coleen and thinking I was always much tinier than her and now she was smaller than me.'
Ellison and husband Robbie Tickle welcomed their son Bobby in February 2010 after a gruelling 92-hour labour.
Bobby's arrival came a few months after they wed in Mauritius in October 2009 - 18 months after they started dating.
The new DVD, which is co-presented by celebrity personal trainer Elia Siaperas, sees Ellison go through a five step workout, including Fat Blaster, Tone Blaster, Box Blaster, Power Blaster and Belly Blaster.
