It is a boy, again, for Will Ferrell and his wife, the actor's publicist said Tuesday.
Mattias Ferrell was born early on Dec. 30, Matt Labov said.
Ferrell, 39, and Viveca Paulin were married in 2000. They also have a 2-year-old son, Magnus.
Ferrell earned a Golden Globe nomination last month for his role in the film "Stranger than Fiction." His other recent screen credits include "Curious George" and "Talladega Nights: The Battle of Ricky Bobby."
