Father's Day 2011: James Van Der Beek, Drew Lachey celebrate with an early cook-out

New dad James Van Der Beek joined Drew Lachey and New York Jets running back Shonn Greene as they rang in their very special weekend with a "First Father's Day Cook-Out" in New York, courtesy of Pampers.

Joining the celebrity pops was expectant mom Ali Landry and her hubby, Alejandro Monteverde. Of course, the little ones were all on hand for a little quality time and a photo op with their dads, as well.

Check out a few photos from Thursday's event below. How freaking adorable is little Olivia Van Der Beek? Excuse us while we go find a baby to snatch -- Kidding! Kidding...

Happy Father's Day to all you proud papas out there. Hope you have a wonderful weekend.
