This is how they roll—literally! Halle Berry and Jimmy Fallon went head to toe on a crash mat during the Tonight Show on Tuesday, July 8, forming a human hamster wheel and somersaulting over each other with amazing skill.

The 47-year-old actress was wearing a figure hugging black and white dress for the show segment, which required host Fallon to lie on the floor and grab her ankles before the X Men days of Future Past actress made a dive over the top of him, propelling the pair into a rolling motion.

"I'm not going to peek, I'm not going to look [up your dress]," Fallon promised Berry as she moved into position, before the pair wowed the audience with five impressive forward rolls.

Berry, who looks remarkably slim since giving birth to son Maceo just nine months ago, has been making a return to the spotlight in recent weeks as she promotes her new TV series Extant. On Monday, July 7, during an appearance on The Late Show with David Letterman, Olivier Martinez's wife revealed that she believes in aliens.

"I don't believe we are the only species in existence," she told the show host. "My ego doesn't tell me that we're the only ones who survived…it might take us 20 years to get to those other life forms, but I think they are out there."
