Look out, Carol Burnett
! Cameron Diaz
is piling on the sass to portray the famously hardhearted Miss Hannigan in the movie remake of Annie
The actress, 41, Tweeted a photo of herself in costume – big hoop earrings, a heap of thick chain necklaces (one of them spells out "HBomb"), dark makeup and even darker roots.
"I want you to meet someone," Diaz writes in the caption
. "Her name is Ms. Hannigan. She ain't nice and she ain't pretty. #Annie"
Diaz plays opposite 10-year-old Quvenzhané Wallis, who stars in the title role and was nominated for an Academy Award
for her precocious film debut in 2012's Beasts of the Southern Wild
Diaz will be singing and dancing in the film, which also stars Jamie Foxx
, Rose Byrne
and Bobby Cannavale
is scheduled to hit theaters Dec. 19, 2014.
