Zoe Saldana, Bradley Cooper's Mom Have a Girls' Date

Amid relationship rumors between "Avatar" star Zoe Saldana and top actor Bradley Cooper, the 33-year-old actress stepped out to lunch and an afternoon movie last week with Cooper's mother, Gloria Cooper.

Saldana was spotted with her younger sister, Cisely Saldana, and Gloria Cooper in Los Angeles on Saturday, Feb. 18. The three ladies got lunch together at the California Pizza Kitchen, and then attended an afternoon showing of the romantic new release "The Vow," starring Channing Tatum and Rachel McAdams.

Paparazzi snapped photos of the threesome as they walked through Los Angeles. Saldana wore black skinny jeans, a black peacoat and black sunglasses, while Cooper wore black sneakers, leggings and a black windbreaker.

Sources close to the couple confirm that Bradley and Cooper began dating in December, although they have kept their relationship very low-profile since.

"[They] are totally dating," a close friend to the couple previously told The Celebrity Café.

This is not the only woman who has rubbed elbows with Cooper's mother. Cooper's previous girlfriend of two years, Renee Zellweger, had been seen on numerous occasions spending time with Gloria Cooper before the two celebrities split up last spring. 

According to The Celebrity Café, Cooper is very close to his mother, who moved from Pennsylvania to Los Angeles last year after Cooper's father passed away.

After splitting from Zellweger, Cooper had short flings with pop singer Jennifer Lopez, actress Olivia Wilde and French actress Melanie Laurent.

Saldana split from fiancé Ketih Britton, also an actor, in Nov. 2011.

Cooper and Saldana are said to have sparked their romantic tryst playing a married couple in their upcoming film, "The Words."
