It's a pair you probably wouldn't expect to see together.

Former Republican presidential candidate Mitt Romney bumped into rapper 50 Cent before filming an appearance on "The Tonight Show."

"With my dad as he gets ready to go on the tonight show w @jimmyfallon," Mitt Romney's son, Matt, wrote on Instagram. "We ran into @50cent who suggested switching wardrobes for the show."

Some have speculated whether the rapper is a Republican. Over the years, 50 Cent has offered praise for former President George W. Bush and said he sees a lot of himself in him.

Romney's appearance on "The Tonight Show" aired Wednesday night.
