It was a busy night at the STK L.A. Anniversary party in West Hollywood on Wednesday, but Ryan Phillippe
managed to slip inside relatively unnoticed with gal pal Paulina Slagter.
"Ryan drove in through the garage to avoid paparazzi, and he was brought into the restaurant through the kitchen," a source tells PEOPLE. "He and Paulina were very cute and held hands at their private table, tucked away from the rest of the crowd."
Slagter, who is reportedly still in college, and Phillippe, took in the sounds of Bibi McGill, the touring lead guitarist for Beyoncé
, who did a few special performances at the ONE Group's trendy eatery throughout the night, to honor its four years in existence.
David Spade, Taryn Manning and a Kendra Wilkinson
-less Hank Baskett were also in tow for the festive evening.
"Hank left in his Cadillac with a guy pal," an onlooker says. "When asked where Kendra was by a random partygoer, he said she was with her mom in San Diego. He couldn't have been nicer to fans who approached him." – Jennifer Garcia and Dahvi Shira
