According to multiple media reports, the 38-year-old actress wanted to cover her bandage from recent surgery on her neck.
A source told E! News that Theron is doing "fine," after minor surgery to correct vertebrae she injured on the set of 2005's "Aeon Flux."
"It was no big deal and a very minor procedure," the source added.
"It's been bothering her a lot lately so she had surgery to correct it and they had to go through her neck," another source told US Weekly.
Theron joined other famous actresses -- like Kerry Washington, Nicole Kidman and Amy Poehler -- for the Variety event, which honors philanthropic industry leaders.
