Madonna, the matriarch of pop, invited adorable living meme and K-pop sensation PSY to perform what will most likely be his lone hit, 'Gangnam Style,' at her Madison Square Garden concert on Nov. 13.

PSY performed his record-breaking hit in a demonically red suit while Madge and her dancers rode their imaginary ponies and swung their pretend lassos to the appreciative cheers of the crowd.

Earlier in the show, Madonna promised the audience a special surprise -- which was of course PSY himself, who'd flown “all the way from Frankfurt, Germany” just to participate in the concert.

Because when Madonna calls, you answer. Even if it does involve hopping a transcontinental flight to help an aging pop star retain her relevance.
