Which reality TV star just had a baby boy?

There’s no such thing as announcing the birth of your baby with 27 words in a newspaper column anymore.

These days, it’s all about telling the world via Twitter.

The latest celebrity to do so is former The Hills star Kristin Cavallari. She and her finance Jay Cutler welcomed their first son Camden into the world. And (surprise, surprise) they announced it on Twitter:

“We are thrilled to welcome Camden Jack Cutler into the world, He was born this morning weighing 7lbs 9oz. Everyone is doing great!”
