Actress Charlize Theron reportedly forgot her bag when she needed to pay for a $3.75 frozen yoghurt. She is said to have paid the bill later along with "a nice tip".

Theron, who has a two-year-old son Jackson, picked up a sweet treat from the Pinkberry store here, but realised she wasn't carrying any cash so left and promised to return later to pay for the $3.75 dessert, reports femalefirst.co.uk.

"Charlize came in and she said she was at the park and didn't have her purse with her, and she got a mini with some toppings which is $3.75," said an employee.

"And she said she'd be right back and then she also said she'd be back within the hour, and then she just kind of took off in the car. I'm hoping she might come back, I don't know though," added the employee.

Over an hour later, the 38-year-old returned to the store and handed over a $100 bill for her frozen yoghurt, telling employees to keep the change.

"She came in and paid her bill. And she left a nice tip. Thank you. Thanks Charlize! I'm just glad she paid the $3.75," said the employee.
