Stiller a dad again

Ben Stiller and his wife Christine Taylor, are celebrating after the birth of their baby boy three weeks ago.

Quinlan Dempsey Stiller was born on July 10 in Los Angeles, weighing in at 8 pounds, 2 ounces.

The low-key Dodgeball and Zoolander co-stars, who celebrated five years of marriage in May, already have a three-year-old daughter called Ella.
