Charlize Theron Works It Out

Charlize Theron leaves a gym in Los Angeles on Monday (April 12) after working up a sweat.

The 34-year-old actress wore a shirt from her own collection! A percentage of proceeds from the sale of every shirt goes toward the Charlize Theron Africa Outreach Project. Pick up your own at GiveAndTakeTees.com!

E! spotted Charlize at a very low-key premiere of The Square, an Australian film, in L.A. last week.

“She was totally dressed down and casual in leggings and a little knit cap,” a spy said. “She was one of the first people to walk into the theater.”
