Taking to a stage with a backdrop of red velvet curtains and jazz club soft lighting, Anne and Jimmy performed renditions of classic rap song together. Yes, you read that right - with Jimmy on piano and accompanying vocals and Hathaway taking to the mic, the pair jazzed up some of hip hop's most well-known hits to cheers of excited disbelief from the crowd.

"Hey Anne," said Fallon. "Yeah Jimmy?" Hathaway replied huskily. "Whaddaya say we break 'em off a little something west coast style?" he proposed. They then broke into a Richard Cheese-style cover of Snoop Dogg's 'Gin and Juice' before heading into a lounge rendition of 50 Cent's 'In Da Club,' and topping the performance off with Kendrick Lamar's 'B***ch, Don't Kill My Vibe.'

The audience roared with laughter at the many swearwords the pair came out with, especially went Fallon broke into a tinkling piano solo. "Jimmy you can't do that to me, it gets me so hot," Anne said. The usually reserved actress embraced the opportunity to show off her talent for comedy and singing and at one point hitched herself onto Jimmy's piano for an impressive vocal solo. "Oh you dirty, Hatha-hating b***ches don't kill my vibe," she sang, referencing the name given to her critics.

The performance ended with roses flung from the audience amidst wild applause. Soon after, Anne took to Jimmy's sofa to discuss her little-known affection for rap. She insisted that she is actually "a big rap fan," telling Jimmy: "Right now I love really Kendrick Lamar, I really love him."

She even admitted that she had really wanted to perform Kanye West's Mercy in their medley and once more brokeinto song as she said "Can you imagine how much fun it would be to Broadway-up, 'Roll my weed on that ass, that's an ass-tray'?" A chuckling Fallon replied: "I'm going to get that tattooed on my lower back - That's poetry!"

Considering her singing voice was so unexpectedly powerful, she was asked whether she'd ever considered performing in a Broadway show. "I would love to do a show, I just haven't found the right one," she replied, adding "There's a couple I've come close and they fell apart at the last minute." Are they available for wedding receptions?
