The model, 33, has found the time to hit the gym too, and got stuck into a gruelling regime with American personal trainer Ashley Borden.
Ashley was seriously impressed by Kelly's fitness levels, and tweeted a snap of her new client lifting some MASSIVE weights!
She Tweeted: "@IAMKELLYBROOK first time doing Deadlifts! U r so easy to coach :) great job."
Kelly must have been chuffed with the praise, as she quickly re-tweeted the post to her own followers.
She's been in the States since October, and got to work with Ashley as soon as she landed. She's been sharing her progress online ever since.
Kelly has also been showing off her incredible figure with her new lingerie range for New Look.
And, if rumours are to be believed, we bet a certain former Blue Peter presenter (yup, we're looking at you Gethin Jones) will have enjoyed catching a glimpse of Kel in her workout gear.
After all, the pair are rumoured to be pretty keen on each other right now.
