All of the Kardashian girls and their mom Kris Jenner were in attendance, but the real star of the party in Beverly Hill Friday was Kourtney's adorable baby Mason Dash Disick.
As RadarOnline.com was the first to report, Mason, whose dad is Kourtney's boyfriend Scott Disick, came into the world in December.
The party at Il Cielo restaurant was a ladies-only affair, except for Mason that is. His aunt Kim left boyfriend Reggie Bush at home. Aunt Khloe's hubby, Lamar Odom was left out as well, although the newlyweds reportedly have babies on their near-term schedule.
