AceShowbiz - Charlize Theron made a group of mums' night by surprising them during a screening of her new film "Tully". The actress made an appearance at a Los Angeles theater on Monday night, April 16 just as the comedic drama was about to start.

"Go, mommies, go, mommies," Theron said as she appeared before them during a Mom's Night Out Event at the Arclight cinema in Culver City with co-stars Ron Livingston and Mackenzie Davis.

Theron marked the occasion in a video post on Instagram. "Love a good surprise!" she wrote alongside the footage. "I know how tough it is for us parents to get a night out at the movies so I appreciate you all coming out to see #Tully!"
