Ice Cube was so fired up after Team Power won the BIG3 title over the weekend, he went to the locker room and kicked off the champagne-spraying party all by himself ... and TMZ Sports has the video.
Cube actually got to the locker room so fast, he beat some of the players to the celebration -- but when Corey Maggette, "Big Baby" Davis and "Birdman" Anderson arrived, they got the full spray treatment.
It all went down Friday night at Barclays Center, where Team Power took on (and beat) 3's Company -- comprised of players like Baron Davis and Drew Gooden.
