"My family, definitely," says the TV presenter, who has a 19-month-old son, Camden, with her American-footballer husband Jay Cutler and is expecting another son. "I hate being away from Camden for even a day."
She and Jay, 30, are expecting their second bundle of joy in May and her Chicago Bears quarterback husband is clearly pulling his weight.
"The last few months, when I’ve been busy, it’s not been the football season so he lets me sleep in pretty much every morning," the 27-year-old tells HELLO! "And he’s really taken over the daddy duties, which is great considering how pregnant and tired I am.”
Kristin, who found fame on reality TV shows Laguna Beach and The Hills before branching out into fashion with her own shoe and jewellery collections, has been busy filming The Fabulist, a talkshow in which she and a panel of taste-makers discuss the latest fashion, beauty and lifestyle trends.
Her dream guest? That would be Kate Moss. "I’m sure it will never happen but if she came on, I'd be the happiest person in the entire world," says Kristin. "She’s so effortless and chic. I love that she’s sort of a bad girl too," she adds, laughing.
The presenter's own party days are behind her now that she is a mum, she says. "I used to love going out or having dinner with girlfriends and I still do that sometimes. But if I could choose, I'd be at home playing with Camden all day, every day,” she says.
Hosting The Fabulist means she has to fly weekly from Chicago to New York for a day or two of filming, but she keeps in touch with Camden and Jay via Skype and can’t wait to welcome their second son into the fold.
"I have relatively easy pregnancies and the first one I loved because it was so new and exciting," she says. "But with this one, it feels it's dragging on a bit because I've done it before. Now I just wanna meet the little guy and see what he looks like."
The Fabulist starts on E! on Sunday at 6.30pm
