Sorry, ladies. Boston Celtics star Jayson Tatum is off the market. Jayson confirmed he is "Boo'd Up" with Grammy-winning singer Ella Mai.

Apparently, they have been an item for years and managed to keep their love a secret.

BSO was the first to report that Jayson was dating Ella Mai over three years ago.

The perfect couple was spotted partying at Michael Rubin's 4th of July all-white party in the Hamptons over the weekend.

Twitter users were shocked to see the couple together in photos from the party.

"I'm really gonna dedicate my life to hating on Jayson Tatum," someone tweeted. "You couldn't be like the rest of these NBA players and f*ck IG models? You had to f*ck with Ella Mai?????"
