Vince Vaughn is quite the doting father!

The 41-year-old Couples Retreat actor and his wife, Kyla Weber, welcomed daughter Locklyn Kyla on December 18, 2010 -- and only Us Weekly has the first exclusive photos of the doting parents fawning over their adorable tot in Chicago on Wednesday!

At the time of her birth, Locklyn Kyla weighed 7 lbs. and measured 20 inches long. She is the first child for Vaughn and Weber, a Canadian real estate agent, who wed in January 2010.

During an appearance on The Ellen Degeneres Show in January, Vaughn, who split with Jennifer Aniston in 2006, joked that he doesn't like to use his daughter's given name.

"If I just call her 'Baby' then she'll love the movie Dirty Dancing but she won't know her proper name," the funnyman quipped. "No one puts her in a corner."
