The 25-year-old star of "The Hills" gave birth to her first child with fiance Jay Cutler this morning -- and she tweeted the news herself.
"We are thrilled to welcome Camden Jack Cutler into the world," Kristin posted moments ago. "He was born this morning weighing 7lbs 9oz. Everyone is doing great!"
While Camden is the couple's first kid, she's not opposed to having more ... and soon!
"We were talking about the possibility of having another kid right away and then getting married so we can have two kids close in age," Kristin recently told Glamoholic. "We want four kids, so we're thinking maybe have one more, then get married, then have two more. But we'll see -- it all depends on how the first one goes."
