Sandra Bullock is paying tribute to the late Maggie Smith.

Hours after Smith's sons Toby Stephens and Chris Larkin confirmed news of the star's death at 89 on Friday, Sept. 27, Bullock, who worked with the late actress on 2002's Divine Secrets of the Ya-Ya Sisterhood, tells PEOPLE, “How lucky am I to have sat in quiet corners with Maggie and a glass of wine."

"Her stories, her wicked sense of humor and her gentle advice are all things that have made my life sweeter," Bullock, 60, adds.

The pair costarred with Ellen Burstyn, Ashley Judd and James Garner among an ensemble cast in Divine Secrets of the Ya-Ya Sisterhood, based on author Rebecca Wells' 1996 novel of the same name. The movie follows Bullock's character Siddalee "Sidda" Walker as she revisits her childhood in Louisiana and reconnects with her mother Vivi (Burstyn) and Vivi's childhood friends after they kidnap her.
