Having already fathered two children, actor Will Ferrell probably knows all about baby changing bags, all in one baby suits and travel cots.

However, he's likely to be investing in all this gear again after welcoming his third child into the world over the weekend.

Viveca Paulin, the comic's wife, gave birth to Axel on Saturday (January 23rd 2010), but the happy news has been under wraps over the past few days.

The tot joins three-year-old Mattias and five-year-old Magnus in the 42-year-old comedian's household.

Ferrell become a father again just hours after appearing on the last ever Tonight Show with Conan O'Brien, where he sang Free Bird.

He has previously offered parenting tips in his own inimitable style, telling Parade magazine: "Don't let them play in old, abandoned refrigerators."

Ferrell is best known for starring roles in movies such as Anchorman: The Legend of Ron Burgundy and Wedding Crashers.ADNFCR-3005-ID-19583378-ADNFCR
