Renee Zellweger bonds with boyfriend's mum as she joins Reese at designer event Renee Zellweger might prefer to keep her romances as private affairs, but it seems her relationship with Bradley Cooper is going from strength to strength.

And, importantly, she has had the seal of approval from the actor's mother, Gloria, whom the star chose as her special guest when she went along to the opening of a Vera Wang store in Los Angeles.

Enjoying the chance to bond over designer dresses, the two ladies behaved like old pals at the event. One source telling People: "They looked like the best of friends."

"They were laughing, chatting throughout dinner. They are definitely close."

Renee, 40, and Bradley's mum apparently had the chance to really bond at Christmas.

The blonde actress spent the festive period with the 35-year-old Hangover star - whom she was first seen stepping out with last summer - and his family.

At the fashion bash Renee and Gloria mingled with celebrities including Reese Witherspoon, American Idol judge Kara DioGuardia and Forgetting Sarah Marshall actress Mila Kunis – the long-term girlfriend of Macaulay Culkin.

Reese – whom British Prime Minister Gordon Brown famously mistook for Renee – showed off her slim-line figure in a silk purple dress.

And just like Renee, the mum-of-two arrived on the red carpet without her reported love interest.

Following her split from Jake Gyllenhaal two months ago, Reese is said to have found love again with handsome Hollywood agent Jim Toth.
