Always up for hilarious hijinks, Cameron Diaz showed up at “The Tonight Show Starring Jimmy Fallon” and played a joke on unsuspecting tourists on Wednesday (April 30).

While promoting her new movie “The Other Woman,” the “Mask” starlet joined Fallon in a Top of the Rock photobomb lampoon in which ordinary people were asked to pose on the roof of Rockefeller Center for a fake website.

Of course during the photo session, Jimmy and Cameron came out behind the various folks and did everything from “Charlie’s Angels” poses to a “Lady and the Tramp” moment with a hoagie.

Earlier this week, Diaz admitted to “Watch What Happens Live” host Andy Cohen, “Yes I have been with a lady,” when he asked, “You have said you think all women have been sexually attracted to another woman at some point- have you yourself ever swam in the lady pond?”
