Cameron Diaz is so funny and fun-loving, we're not surprised she's a bit of a prankster.
She was just on The Tonight Show Starring Jimmy Fallon and she's Jimmy's first repeat guest! Woo!
After celebrating that, they got down to the business of babies… like Drew Barrymore's baby!!
They spent a minute gushing over baby Frankie! What a cute baby name!
Then things turned to the time Cameron pulled a prank on Jimmy's then six-week-old baby Winnie!
Yes, you heard us, she pranked an infant. There's even photo proof (below).
Her excuse? The baby fell asleep first at a party so pranking her was fair game!
Check out the video (below) to find out exactly what went down!
