Lady Gaga is ready to hit the big screen in the upcoming flick Men In Black 3 alongside Will Smith and Tommy Lee Jones, according to online reports.

Smith, who starred in the first two films, revealed the casting news while in Rio last week. He told reporters:

    "We have a couple of celebrity cameos, but I think I can not reveal who they are. We must keep as a surprise that Lady Gaga appears."

Nicole Scherzinger is also joining MIB3 which hits theaters in May.
