Maroon 5 and Kanye = BFFs

Kanye West made a brief, surprise appearance at last night's Maroon 5 concert at Madison Square Garden, to the delight of the packed arena.

According to a TMZ staffer's mom (yes, Maroon 5 has 60-year-old fans), frontman Adam Levine introduced his "special friend," and the Garden went ballistic when Kanye entered to perform his duet with Adam, "Heard 'Em Say."

Kanye did his one song ("I could barely recognize him because of those big glasses he wears," said TMZ mom), waved and walked off. Kanye not hogging the spotlight? That's a new one!

Later last night, Kanye got even more groove on downtown at Tenjune, where In Touch magazine held its fifth anniversary party. Everyone from Emmy Rossum to Janet Jackson to Greasy Bear to Kenan Thompson to Matthew Isaacs, whose Bloc Group ran the show, packed the room as 'Ye tore through a frenetic set that included everything from "Golddigger" to "Good Life."
