Meek Mill did NOT spend one of his final nights before house arrest with his main chick -- Nicki Minaj -- he spent it with MANY chicks ...as in the Philly strippers he showered with $75k!!
Meek hit up the Vanity Grand Cabaret: Philadelphia Premier Gentlemen's club Sunday night for Future's after-party ... but the night was less sad, going away and more celebration ... of ass.
We're told Meek brought his artist Chino MMG, who just survived a shooting a few days ago ... so you know he was ready to party.
Of course, the fact he wasn't with Nicki is a strong sign there's trouble in paradise ... as we've reported, the couple's been feuding.
As for his house arrest ... the Philly D.A.'s Office tells us everything's set for Meek to go under lockdown ... including his monitoring device and clearing his home of contraband and weapons.
