Renee Zellweger

Renee Zellweger is proving her devotion to boyfriend Bradley Cooper's family - she invited the actor's mum to be her date at the recent VIP opening of a designer clothing store.

The couple has been romantically involved since last year (09), but recently denied reports they are set to move in together after they were seen househunting in January (10).

And Zellweger seems to be popular with Cooper's mum Gloria - the matriarch accompanied the Bridget Jones's Diary star to the launch of Vera Wang's Los Angeles store on Tuesday (02Mar10).

A source tells People.com, "They looked like the best of friends. They were laughing, chatting throughout dinner. They are definitely close."

The actress bonded with the Coopers after spending the Christmas holidays with the family.
