The 47-year-old actress revealed as much in an interview for the Feb. 27 issue of The Hollywood Reporter. Mo'Nique won an Academy Award for her portrayal of Mary Lee Johnston in the 2009 film, but was reportedly passed over for new roles because she "didn't play the game."
"There have been people that have said, 'Mo'Nique, she can be difficult,'" the star admitted. "They could probably be right. One of the networks said to [Lee] that I was 'really difficult to work with.' And I said, 'Well, that's funny, because I've never worked with them, but okay.'"
