Last month, Kristin announced that she and husband Jay Cutler are expecting another baby boy to join their adorable little family.
But instead of treating herself to lots of guilty pleasures during her second pregnancy, the mum-to-be is still making sure to eat healthily and stay in shape.
And her cravings are pretty guilt-free!
Despite having a sweet tooth, the former reality TV star is being careful not to overdo it and is only eating dark chocolate and ice cream made from coconut milk.
She told Us Weekly: "I crave sweet things, but it's no different than when I'm not pregnant. I pretty much have dark chocolate every day because I don't think it's bad for you, and we get this coconut bliss ice cream made with coconut milk. I'll eat that a lot. It's amazing.
"When we go out to eat, Jay and I always get dessert. He has a sweet tooth, as well."
In fact, Kristin's diet hasn't changed much from before she fell pregnant.
"I'm eating the same I normally do, and I'm working out but I'm not killing myself," she added.
The ex star of The Hills - who is already mum to son Camden Jack - appears to be taking no time off from her hectic schedule over the last few months, since she has been seen out and about on numerous occasions.
Back in February, Kristin lived every girls' dream as she promoted her shoe line in Las Vegas - surrounded by plenty of gorgeous heels.
And just this weekend, 27-year-old Kristin and her growing bump stunned in a black lace Balmain dress at Elton John's Oscars Viewing party. Talk about yummy mummy!
In contrast to the American star's tame pregnancy cravings, fellow mum-to-be and UK singer Kimberley Walsh has admitted that she is already craving lots and lots of chilli.
She tweeted recently: "So my only craving so far is spice.....literally cannot get enough of chilli these days ha #passthechillioilplease anyone else have this?!"
