Ellen Pompeo and her music exec husband, Chris Ivery, helped kick off Sergio Tacchini’s STLA pop-up shop in West Hollywood on Thursday.

Pompeo played a game of tennis with Roc Nation Sports exec Shawn “Pecas” Costner and “Ray Donavon’s” Dash Mihok as models “broke out in old-school dancing,” according to spies.

“They turned the tennis court to a full-blown dance arena. Pusha T surprised everyone and performed. It was an intimate group,” a source told us.

Stylist June Ambrose, Eddie Huang, Bevy Smith and Pompeo’s “Anatomy” co-star Justin Chambers were also on deck for the celebration.
