Vince Vaughn and wife Kyla Weber welcome daughter, Locklyn Kyla Vaughn

It's a girl for Vince Vaughn and wife, Kyla Weber. The happy couple welcomed daughter Locklyn Kyla to the world on Saturday morning (Dec. 18).

This holiday bundle of joy is the first child for both parents, weighing in at 7 lbs. and measuring 20 inches long. "Both of them couldn't be happier to welcome their sweet little girl into their family," a friend of the actor tells People,

Vaughn wed Weber, a Canadian real estate agent, in January 2010 and by July the duo announced their pregnancy. Talk about a big year.

Congrats to the new parents!
