The Austin Powers: International Man of Mystery star and his partner, Kelly, welcomed a girl in New York City on Monday (02Nov15).

A spokeswoman confirmed the news, telling the Associated Press the couple is "elated" following the birth of Paulina Kathleen, and both mother and baby are doing well.

The couple, which wed in 2010, is parents to two other children - a son named Spike, who was born in 2011, and daughter Sunday Molly, who arrived last year (14).

"Anyone who tells you fatherhood is the greatest thing that can happen to you, they are understating it. I am the happiest I have ever been in my life," Mike previously gushed about the joys of parenting.

"I knew I wanted to be a father, I didn't know it was going to be this awesome or that my kid would come out so beautiful and lovely."
