Screw Gatorade -- last night Los Angeles Lakers hero Ron Artest took a celebratory bath in VODKA!
Still wearing his jersey from the NBA Championship game earlier in the evening -- Artest strolled into the Wonderland nightclub in Hollywood last night around 1 AM ... and the place went INSANE!!
We're told Ron grabbed the mic and celebrated with the crowd ... even pouring shots of Patron for all of the Lakers fans.
Check out the footage from inside the club!
