Tom Cruise, is that you? Ab-solutely! The "Valkyrie" star was photographed in Rio de Janerio flashing his pecs and lean abs!

Cruise told our Terri Seymour he has tried different workouts for different films, but he has never resorted to anything "extreme." Rumor is the 46-year-old actor was inspired by pal David Beckham, and that the L.A. Galaxy star created a diet regimen for his bud.

It's also rumored Cruise is bulking up for the physically challenging stunts in "Mission: Impossible IV."
