Kimberly Stewart & Benicio del Toro Celebrate Her Birthday in L.A.
West Hollywood, CA
to my to do list
Kimberly Stewart celebrated her 33rd birthday with dad Rod, stepmother Penny Lancaster and brother Sean at Bootsy Bellows in West Hollywood on Friday night.
In a curve-hugging black dress, Kimberly chatted with friends while Rod kept a low profile. The 67-year-old rocker didn't move from his seat when the DJ played his 1978 hit, "Da Ya Think I'm Sexy?"
Benicio del Toro, who has a daughter, Delilah, with Kimberly, also joined the soiree briefly. He arrived with a few pals, wearing a baseball cap.
"The two seemed to be on good terms and got along well," a source tells PEOPLE. "Although he didn't stay for long, clearly he was there to make an appearance for Kimberly."
The festivities wrapped up around 1:15 a.m. when the Stewart family parted ways.
