Charlize Theron Says She Is 'Very Fat Right Now'

The actress reportedly gained 30 pounds for the upcoming comedy, "Tully."

Charlize Theron ditched her usual form-fitting gowns for a looser frock at amfAR Inspiration Gala in Los Angeles Thursday evening.

The reason for the 41-year-old Oscar-winner's baggier attire? A curvier figure.

"Yes, I am very fat right now," Theron said after Chelsea Handler joked about her weight gain.

According to People, Charlize gained 35 pounds to play a mother of three in the upcoming comedy, "Tully." Theron herself has two adopted children.

This isn't the first time the actress has undergone a dramatic body transformation for a film role, however. Back in 2004, she gained over 30 pounds for her Academy Award-winning role in "Monster." She also shaved her head for "Mad Max: Fury Road."
