Jae Crowder spent much of his Labor Day weekend squaring off with the mother of his daughter on social media.

The Jazz forward alleged Dana Lambert had cheated with 76ers forward Robert Covington, tagging the two on his Instagram story and writing, “Lil Robert y’all ain’t gotta be sneaky.” But Lambert replied to the accusations with a slew of her own.

“Ain’t nobody being sneaky but u wanna let ppl know what being sneaky really is ‘dad?'” Lambert posted, according to a screen grab obtained by SportsGossip.com.

She continued to fire expletive-filled shots at Crowder, calling him a “f–king clown” and a “f–king idiot.”

“U f–ked my friend!” she wrote, tagging her friend. “While jada and I were asleep!”

Lambert threatened to air more dirty laundry.

“U so worried about making your flight u bout to really be sorry for a bunch of more s–t u need to worry about!” she continued. “If u f–k with me again all the s–t about u and your nasty ass married ass team mates are going up! @bossmann99.”

Though Lambert’s messages are no longer available on her Instagram story, Crowder took to social media Tuesday, writing, “New Phone #.”

The two have a daughter, Jada, together.

Crowder has played for the Mavericks, Celtics, Cavaliers and Jazz in his six-year career.
