Whitney Port says she's not having sex while pregnant: 'It's so not for me!'

Whitney Port admits that her sex life isn't what it used to be now that she's very pregnant.

The former star of The Hills got candid with The Insider's Keltie Knight, actress Becca Tobin and stylist Jac Vanek on The Ladygang podcast about how her growing baby bump has affected her time with husband Tim Rosenman in the bedroom. "It is so not for me! It's not," Port exclaimed when asked by Knight what it's like to have sex while pregnant. "I feel so uncomfortable with my body that I can't get into the mood. Like, I can't feel sexy."

The 32-year-old reality star confided that she and her husband do "other things," but "once the belly really started happening," she really wasn't into lovemaking.

When asked if Rosenman likes how her body is changing, Port admitted, "No, because I don't."

"I think if I was one of those pregnant women that loved it and was confident, then he'd be into it," she explained. "I think I've turned him off of it because I'm like, 'Don't look!' I'll even not say anything and he'll see me getting undressed and be like, 'I'm not looking, I'm not looking!'"

In addition to Port being pregnant, Hills alums Heidi Montag and Lauren Conrad are also expecting, while Kristin Cavallari and Audrina Patridge already have kids. "I don't really care," Port said of the so-called Hills baby boom. "I mean, I'm like so happy for them, but I don't really keep in touch with them."

The MTV star did confess that she was "surprised it took so long" for Montag and her husband, Spencer Pratt, to have a child, because "they've been together for so long."

While fans of The Hills may have seen Pratt in the role of a villain of sorts on the show, Port insisted that he has a softer, smarter side that she got to see when the two went to Crossroads High School together. "I always got such a kick out of Spencer. He's so funny and actually really, really smart," she noted. "I was really bummed [about] how he played out the whole thing, because I didn't ever really see that side to him. Spencer and I have always gotten along. We just have a history that people don't even really know about."

In an exclusive interview with ET, Montag and Pratt admitted that they're still not ready for the birth of their first child.. "Definitely in way over my head here," Pratt quipped. "I'm glad Heidi's pretending that she's not!"

"We've been moving so much, and I haven't had the chance to even do the nursery," Heidi, who's about six months along, added. "I have no idea what I need, and the baby registry and the baby shower... so, I definitely need the next few months to prepare."
