The Hills are coming alive with the sounds of congratulations. Former star Kristin Cavallari gave birth to her first son with her fiancé, Chicago Bears quarterback Jay Cutler, earlier yesterday morning and she has already received plenty of warm messages from her former co-stars.

"Congrats!!!!!" Audrina Patridge wrote. "Can't wait to see Camden. So happy for you!" Audrina and Kristin had feuded on the show over Audrina's on-again, off-again beau but made nice after the show wrapped and were even spotted chatting at a recent event.
"Congratulations on your new baby boy!" tweeted Heidi Montag. "One of life's greatest gifts! Enjoy mama! Oxxo." Heidi and her husband Spencer Pratt have yet to have children of their own and after some not-so-smart spending, the two have ended up back at Spencer's dad's house where they don't have to worry about paying rent.
Spencer also tweeted his well wishes to Kristin. "Congratulations on Camden's birth! I'm free to be the Godfather if you need one!" Don't hold your breath, Spencer. If any of The Hills' boys got that role, it would surely be Brody Jenner, who Kristin has been friends with for several years.
One person noticeably absent from the congratulatory messages is Kristin's former nemesis, Lauren Conrad. Is there still tension between these two?
