MTV Twitter Roundup: K-Cav Receives Many Congrats On Her Pregnancy

Kristin Cavallari glows at Cirque du Soleil's 'OVO' earlier this month.

Earlier this week, we teamed up with the internets and collectively broke the news that former "Hills" star Kristin Cavallari confirmed she's expecting a child with her main squeeze Jay Cutler. The (re)newly engaged couple called off their wedding some months back, but have since reconciled, and, as evidenced by said news, gotten busy. As soon as webbers posted their baby blabber, everyone from "Exes" competitor Paula to Cavallari's old chum Audrina Patridge typed up cutesy 140-character messages to congratulate the mom-to-be on her little bundle-to-have.

And if you were curious how Cav kept the goss under wraps for so long, a recent tweet explains it all. Evidently she'd been using social media to throw people off her scent by feeding them false information. (Kristin, that's so unlike you!) Heidi Montag also tweeted a congrats of sorts, but it was quickly pushed down toward the bottom of her timeline by an excited note regarding the premiere of "The Challenge." We can't blame her; "Exes" is kinda awesome.

Check out what they and other MTV stars were up to this week:
