Chris Hayes Baby: MSNBC Host Announces Birth Of Daughter Ryan

It's a girl! MSNBC's Chris Hayes became a father with the birth of his daughter, Ryan Elizabeth Shaw-Hayes, on Monday.

He announced her arrival on Tuesday, tweeting: "I'm a daddy! Our daughter Ryan Elizabeth Shaw-Hayes was born yesterday at 8lbs 3oz. She's perfect! Mom & daughter are both doing great." He also tweeted a picture of his new daughter.

The baby is Hayes' first child with wife Kate Shaw. The MSNBC host is clearly relishing fatherhood. He tweeted that he will be hosting his show this weekend "though it kills me a little to pull myself away from Ryan," and joked that she was born on the optimal day for his show schedule.

This Thanksgiving, he told The Huffington Post that he was thankful for his "impending fatherhood, my wife, my family and friends."
