Charlize Theron Dons A Bikini While Celebrating Her 38th Birthday

Charlize Theron frolicked in a bikini while on vacation celebrating her 38th birthday.

Theron wore the two-piece, yellow-and-blue swimsuit last week in Hawaii, where the "Mad Max" star and 17-month-old son Jackson had some fun lounging waterside and snorkeling together at a sun-drenched resort.

Hollywood trainer Fedele De Santis says Theron maintains her fabulous figure with the help of a ballet-based workout. And she is a dedicated trainee.

“Charlize is an extremely serious, focused, professional, no BS, balls-to-the-wall client,” De Santis told Shape magazine in June. “She is so tenacious — my nickname for her is thundercat!”

The actress, who turned 38 on Aug. 7, celebrated her birthday early with a dinner party in Rome on Sunday, Aug. 4, according to ABC News. She and friends munched on mozzarella, prosciutto and pasta dishes, drank red wine and ended the night with cake.

“She was in great spirits, looking beautiful and admiring the Roman sky,” a source told the outlet.
