PARADE POP-OFF New York Liberty
It's a bad day to be a champagne bottle ... 'cause Breanna Stewart is grabbing all the bubbly in sight as the New York Liberty parades through the streets to celebrate their WNBA Finals win!!
The 6-foot-4 forward was spotted having a blast as her float made its way down Broadway ... spraying what appeared to be some Ace of Spades before taking a swig right from the container.
Sabrina Ionescu -- who wore a dope Nike custom Liberty jacket for the occasion -- turned the bash into a mini meet-and-greet .
