Heidi's been making it no secret that she's ready to start a family with her heaven-sent hubby, but are you really ready for The Hills to become A Baby Story?

Well, if Heidi's sister-in-law Stephanie had her way, America's Most Hated couple wouldn't be reproducing for quite a while.

When MTV asked Steph whether or not Speidi would make good parents, Stephanie took a loooong pause before responding "Heidi is 22!"

Even Spencer seems to be the voice of reason - for once. Steph says only Heidi's got the baby fever.

"Here's the deal: Basically, Heidi got married; [then] she's like, 'Oh my God, what do I do?' 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.' "

Ooohh, snap! You really have to check out the video below to catch all of Stephanie's inflections. Forget the Lauren/Heidi feud, is there something going on between Steph and Heidi for next season?
