Angelina Jolie recently enjoyed some quality time with Vivienne and Knox, her biological children with ex-husband Brad Pitt.

On Sunday, Jolie seemed to channel her role as Lara Croft in the original "Tomb Raider" movie during her rock climbing activity with the 10-year-old twins. In photos released by Daily Mail, Jolie seemed to be teaching Vivienne and Knox how to scale a rock wall like a pro in California.

One photo of Jolie rock climbing also seemed reminiscent of her role as a spy in "Mr. and Mrs. Smith," which she co-starred in with Pitt. Her character had to climb the side of a mountain, as seen in this still from the 2005 movie.

Another photo from their rock climbing date showed Knox observing as his mother tackled the rock wall with ease, with a staff member on stand-by.

For the activity, the Oscar-winning actress wore a long-sleeve black top and charcoal gray slacks. She also styled her hair in a neat ponytail before scaling the wall at a fitness facility in Los Angeles. Vivienne and Knox also made sure to dress in appropriate clothing for the activity. Knox wore a blue shirt and black shorts over camo pants, while Vivienne also donned a t-shirt and gym shorts.

This wasn't the first time Jolie has been spotted out and about with her children this month. Over the weekend, she took her son Pax, 15, shopping in Los Angeles. Pax and Knox also accompanied her on an outing in the city earlier this year.

This new sighting comes after reports surfaced that Jolie's ex-husband had been spotted getting cozy with Charlize Theron at the bar of LA's Chateau Marmont. The two had apparently been dating for nearly a month prior to this "date." A source told The Sun that Pitt apparently wasn't shy about touching and flirting with Theron and appeared to be in a "really good place."

However, the Sun story was debunked by People magazine, which confirmed that there is no truth to rumors that Pitt and Theron are in a relationship. While the two stars did meet at a commercial shoot last year, nothing ever developed from that.

"They have not been out together recently, and were never dating. Reports of them being involved romantically are false," the source told People.
