Actor Neil Patrick Harris has been known for his incredible singing talent, and on his appearance on James Corden's 'The Late Late Show', he couldn't help but mock the host on winning a Tony Award for a "non-singing role."Determined to defend himself, the two launched into a passionate and hilarious Broadway Riff-Off, singing songs from 'Les Misérables' to 'Chicago' that ranged in styles from heartbreaking ballads to "being sexy."However, getting a bit too sexy on stage also led to a wardrobe malfunction for Neil Patrick Harris.
"When I went down on my knees there, I had a nice wardrobe malfunction and split my pants from my ass to my knee," Neil admitted when they returned from commercial break. "I left it all on the stage for you."
See how it all happened in the video above.
