Steph Curry Absolutely Loses His Mind Over Damion Lee's Game-Winning Shot

Steph Curry was so pumped for his bro-in-law's game-winner on Wednesday night ... he woke up everyone in his house -- and nearly everyone in his neighborhood, too!!

Curry spent part of his off-night from the NBA watching the Suns vs. Mavericks ... and when Damion Lee -- his former Warriors teammate and the husband of his sister, Sydel -- sank an improbable shot to give Phoenix the dub, he absolutely lost his mind.

The 4-time NBA champ and Golden State superstar let out a guttural yell ... before claiming he didn't mind that he was bothering his sleeping kids.

"Come on!!!!" he screamed as his wife, Ayesha, sat on the couch behind him. "Yeah, Dame! Stick with it! Stick with it! Stick with it!"

"The kids are asleep," he added. "I don't care! Stick with it!"

In the background, Curry's youngest child, Canon, could be heard crying -- but it still didn't stop Steph from praising Lee.

The two are obviously super close -- and have been officially family since 2018 ... when Lee married Sydel.
