Tom Cruise may never top his iconic dance sequence from 'Risky Business.' However, he's still a force to be reckoned with on the dance floor — though he's traded in his trademark tighty-whiteys for slightly more elegant attire.

At the recent nuptials of tech heir David Ellison and Sandy Modic, Cruise showed off his signature dance moves by doing the Worm to the Maroon 5/Christina Aguilera chart-topper 'Moves Like Jagger.'

Reportedly, Cruise was inspired to do a little bump 'n' grind after being challenged to a dance-off by another guest at the wedding. Who would have suspected that an IT billionaire's wedding would turn into an impromptu remake of 'You Got Served'? (Certainly not us.) Good to see that couch-jumping hasn't shot his muscles — or maybe the famed Scientologist was just trying to shake out those thetans...

'Moves Like Jagger' climbed to the top of the Billboard Hot 100 in the week of September 10, giving Aguilera her first No. 1 hit since 2001's 'Lady Marmalade' — a significant triumph for the big-voiced chanteuse, whose last album underperformed commercially. It must be quite the coup for Aguilera and fellow 'The Voice' judge Adam Levine to see that the track is beloved by some A-list fans, too!
