Ava's bash was held at the Four Seasons Hotel in Westlake Village, Calif. Locklear, 52, and Sambora, 54, smiled for photos, seen here, with their daughter in the middle of them.
"Ever since I was 5 or 6, I've wanted to be an actress," Ava Sambora recently told Teen Vogue. "I loved attention and would always try to be onstage and in front of people. It was easy to figure out what I wanted to be."
Locklear and Sambora divorced in 2007 after nearly 13 years of marriage.
