Margot Robbie Kept Pet Rat That 'Suicide Squad' Co-Star Jared Leto Sent Her

Find out how she pampers the tiny creature.

"He sent [Margot] a nice love letter with a black box with a rat in it — a live rat," Adam Beach, who plays Christopher Weiss, aka Slipknot, in the movie, told E! News. "It was beautiful. Then he sent bullets to Will [Smith] with a letter."

Guess what? Robbie went method too and kept it.

"If Harley got something from Joker, she'd probably cherish it," the 25-year-old actress told Elle.

"Suicide Squad" is scheduled to hit theaters Aug. 5, 2016.
