In the snaps uploaded to her twitter page, theatre actress Jennifer showed off her golden tan as she posed with her sons and husband.
Jennifer, 30, who used to act in Brookside, has recently shed two stone on the Cambridge Weight Plan, which restricts dieters to just 800 calories a day.
The actress began her weight loss campaign in November, after she feared her size was beginning to affect her health.
At 5ft 7, Jennifer weighted 12st 3lb, and felt unhappy in her size. She has now slimmed to her target weight of 10st 7lbs.
Fans questioned if Jen was simply losing the weight to bring out a fitness DVD - but the actress insisted it was because she just wanted to be able to run around after her two young children.
The star had previously hit back at twitter trolls who attacked her over her post-baby weight in 2013.
The actress wrote: 'To all the horrible ppl commenting about my weight…I gave birth 12 WEEKS AGO! Sort your heads out my baby boy is my priority not my size!!'
