Who knew Carson Daly even had a girlfriend?

Well, he does, and now he's getting a baby to go along with her. The Last Call host and his main woman, Siri Pinter, are going to be parents.

"Carson is thrilled to be a father and they are looking forward to an extra special Thanksgiving this year with family and friends," his rep Heather Lylis told People.com.

The baby is due in the spring.

Congrats!
