*Prince and Madonna have apparently squashed their decades-long feud after the Material Girl turned up at his recent New York concert and cheered him on from the crowd.

The superstars were close friends throughout the 1980s and were said to be dating for a brief time before teaming up to record the track “Love Song,” from Madonna’s 1988 album “Like a Prayer.” But they suffered a mystery fall-out and their relationship turned bitter as they took shots at one another through the media.

In subsequent interviews, Madonna blasted Prince as a “little troll” and criticized his refusal to eat during one dinner date, stating, “He was just sipping tea, very daintily. I have this theory about people who don’t eat. They annoy me.”

Their spat continued throughout the years and Prince most recently took aim at the mother-of-four at a concert in London in 2007, when he quipped, “I got so many hits y’all can’t handle me. I got more hits than Madonna’s got kids!”

But the two appear to have put their differences to rest – according to UsMagazine.com, Madonna was spotted in the audience at Prince’s Madison Square Garden gig on Tuesday (Jan 18), singing and clapping along to his hits.

Prince acknowledged Madonna’s presence by giving her a special shout out from the stage, after joking about the high-price of their concert tickets.

At the same concert, Prince pulled “Gossip Girl” star Leighton Meester on stage from the front row and serenaded her with “I Love U, But I Don’t Trust U Anymore.”

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.
