They also cemented their bond by performing Dionne Warwick's “That's What Friends Are For”
PSY and Snoop Dogg collaborated on new single “Hangover,” and Jimmy Kimmel forced them to collaborate on karaoke during Sunday's NBA Finals post-game show.
Kimmel's mom drove the trio to Los Angeles bar, Boardwalk 11, where they started off a three song set by singing Snoop's 1993 hit “Who Am I (What's My Name),” followed by the American rapper's interpretation of K-pop hit “Gangnam Style.”
They finished strong by singing “That's What Friends Are For,” a song most famous for Dionne Warwick's cover with “Friends” including Dionne Warwick, Gladys Knight, Elton John, and Stevie Wonder.
