Are you ready to LOSE YOUR MIND up in here?!
During Alicia Keys' Madison Square Garden gig last night, her husband Swizz Beatz and his former Ruff Ryder companion DMX hopped on stage and drove the crowd WILD when they spat a few lyrics of the original Ruff Ryder's Anthem…
But THEN they launched into their RAGING 2000 hit, Party Up (Up in Here)!!
And the audience proceded to party their faces off.
Glad to see DMX is involving himself in non arrest-worthy hijinks!
