This is one Gossip Girl who has even more to talk about now.
Leighton Meester found herself in the envious position of being serenaded by none other than Prince on Tuesday night when His Purple Highness pulled her onstage during his concert at New York City's Madison Square Garden.
Yep. As if sitting in the front row wasn't already awesome enough, the actress got "I Love U, But I Don't Trust U Anymore" sung directly to her as well.
But Leighton wasn't the only one there partying like it was 1999...
Later in the evening, other celebs were invited onstage during the performance of "Baby I'm a Star" including Mos Def, Brian McKnight and Jimmy Fallon, who actually went over and played for a bit on the drums.
Leighton's Gossip Girl costar Ed Westwick was also at the big show, along with Casey Affleck, Spike Lee, Donald and Melania Trump as well as Madonna, who got a personal shout-out from Prince himself.
