Shake it up: Jennifer Lopez and Tom Cruise, in character as Tropic Thunder's Len Grossman, performed a hilarious hip-hop routine at the MTV Movie AwardsHe has a reputation for being somewhat uptight.
But there was no holding Tom Cruise back as he performed a jaw-dropping hip hop routine with Jennifer Lopez at the MTV Movie Awards.
The actor reprised his role as Len Grossman, the fat, balding foul-mouthed Hollywood producer character he played in Tropic Thunder.
Movie night: Cruise had earlier launched the ceremony under the guise of profanity-spewing Grossman Bumping and grinding their way across the stage, the pair performed a highly synchronised set, full of cheoreographed moves.
At one point Lopez spanked a willing Cruise, but ticked him off when he attempted to return the favour.
The pair were cheered on by Cruise's wife Katie Holmes, who sat in the front row.
Hip hop style: The pair performed a highly synchronised routine
Bump and grind: Cruise shows he's got the moves during his energetic performanceThe hilarious ended with Cruise making a valiant attempt at doing the splits, which he only half-completed.
Cruise had earlier launched the ceremony under the guise of profanity-spewing Grossman.
In the opening parody, Grossman cast Twilight stars Taylor Lautner and Robert Pattinson as mustached cops, used Michael Cera as a human bookend and yelled at The Karate Kid star Jaden Smith as father Will Smith looked on.
Funny moment: Cruise appeared more than happy to let Lopez spank him...
...But the singer pretended she wasn't impressed when he tried to repeat the moveAlso taking to the stage at the star-packed show was Katy Perry, who performed a duet with Snoop Dogg.
Katy sang her song California Gurls, wearing an sparkly outfit apparently inspired by Wonder Woman.
Christina Aguilera performed a medley of three songs from her new album Bionic.
She shed the black fairytale gown she arrived in for a bodysuit and cape, with a unique accessory - a flashing LED heart between her legs.
They've got the moves: Cruise and Lopez had obviously both rehearsed their action packed routine
Down he goes: Cruise attempts the splits, but only gets half way down [endtext]
