Heidi Montag's 'Baby Fever' Heats Up

Spencer and Heidi Pratt still out of control? Spencer and Heidi Pratt still out of control?

Is there a little Speidi in the works?

According to “The Hills” star Stephanie Pratt, her sister-in-law, Heidi Montag, has “baby fever” – but as for her brother Spencer Pratt, he’s still enjoying the kid-free life.

“Heidi is the one with the baby fever; Spencer is not,” Stephanie recently told MTV News, adding of the recently married couple, “They’re looking for a house.”

Stephanie thinks the recent Playboy cover girl might be taking her motherhood cues from the local bookseller.

“Here’s the deal: Basically, Heidi got married; [then] she’s like, ‘Oh my God, what do I do?’ " Stephanie explained. “She’s like, ‘Thank you, God, for my marriage. What do I do?’ I really feel like she went to a bookstore and saw ‘Newlyweds: The Wife’s Edition,’ and so now she’s like, ‘I still want to get a house with a white picket fence… and then probably a dog, and then we’ll move on to kids. And I want to take cooking lessons.’”

But according to Stephanie, her brother and sister-in-law don’t have the time needed to raise a child – or even a pet!

“I’m like, ‘You don’t have to do that,’ " she said. “I keep telling her, ‘You don’t have to get a dog [either].’ A dog is a kid. They’re just too busy.”
