Pop superstar P!nk joined Guns N' Roses onstage at Madison Square Garden in New York City to help Axl Rose sing the band's 1989 classic "Patience."
"We're going to bring a friend of ours out here," Axl said six minutes into the performance. After entering the stage with a look of pure joy on her face, P!nk took over vocal duties on the song, showing off her talent and range.
Guns N' Roses thanked P!nk later on that night on Twitter to which she playfully responded, "Oh. Yeah. Whatever. No problem."
