It seems Renée Zellweger has a new BFF: Bradley Cooper’s mother Gloria.

The actress brought her boyfriend’s mom to the Tuesday night opening of Vera Wang s Melrose store in Los Angeles, where the pair behaved like old pals. “They looked like the best of friends,” says a source. “They were laughing, chatting throughout dinner. They are definitely close.

Zellweger and Gloria joined Reese Witherspoon, Angie Harmon, Mila Kunis, Kara Dioguardi, Amber Valletta and Olympic gold medalist Evan Lysacek at the opening of Wang’s store.

This isn’t the first time Zellweger has shared time with Bradley’s family. The actress spent Christmas with Cooper and his parents in L.A., and the group was spotted taking a walk on Venice Beach and shopping together over the holidays.

Though Zellwegger and Cooper have been mum about their relationship, they’ve frequently been spotted together since last summer, spending time with each other all over the globe, including stops in New York, L.A., Utah, Spain and Vancouver.

In August, a source told PEOPLE that the couple “get along really well and just kinda click.”

The two were most recently seen together Wednesday morning in L.A., looking at Cooper’s new home in the Pacific Palisades.
