Following Diana Ross’s epic performances at the Hollywood Bowl, her son Evan Ross and wife Ashlee Simpson Ross hosted a Birthday pool party in honor of Evan’s 34th Birthday at their home in Los Angeles. A-listers, musicians, and comedians joined in on the festivities where they enjoyed cocktails by Fun Wine including a Strawberry Rose Moscato, Peach Passion Moscato, and a Red Sangria with fresh fruit. The family affair included Tracee Ellis Ross, who rocked white overalls and a black tank, and Ashlee’s dad Joe Simpson, who was dressed in a head-to-toe matching Gucci shorts set. Tracee Ellis Ross was spotted taking selfies with her brother and sister-in-law next to the Fun Wine’s photo wall which included a baby photo of Evan.

Pretty Little Liars star Ashley Benson was spotted chatting at the bar with comedian Tiffany Haddish laughing about her recent Usher stage performance in Vegas. Comedian Marlon Wayans and Elijah Kelly all played a heated round of basketball by the pool while singer Miguel led a dance-off with tunes spun by DJ Ruckus. Singer Macy Gray was spotted snacking on tasty Jamaican Cuisine from Yaad Island Food Truck. As the sun set, Oscar-nominated actor Terrence Howard jumped on the baby grand piano for an epic happy birthday song session to close out the night.
