Kelly Clarkson is a proud momma. The singer introduced little River Rose Blackstock to the world over the weekend via Twitter, of course. And what a little cutie! The snapshot has the baby, who was born on June 12th to the singer and hubby Brandon Blackstock, wrapped up in blankets laying in a red carriage in front of a house. The carriage even has a rose on it, a nod to the little girl's name. "Here is our beautiful baby girl River Rose; 6lbs 6oz, 18 inches, and the greatest thing on the planet," she captioned the picture. Congrats to the happy, and adorable, family!
