Tristan Thompson was on the receiving end of fans’ wrath after he attempted to flirt with ex Khloé Kardashian in the comments section of her Instagram.

The Boston Celtics player, 30, left three heart-eyed emojis Tuesday beneath a photo of the Good American co-founder, 37, wearing a blue dress on the beach, immediately prompting fans to ask him to leave her alone after he cheated on her multiple times.

“Can you just NOT. You’ve hurt her so many times and now you wanna come put 😍😍😍 on the post,” commented one follower. “You didn’t treat her right so somebody else will. Uggghhh the audacity URKS me Tristan!!!!!!”

“back off dude , leave her live her good life now!!!” begged another fan.

“and there is Tristan daydreaming he will ever be with this beautiful woman again!” wrote a third Instagram user. “Player..grow up ..raise your kid and leave this soul for someone that deserves her👏

“you don’t deserve Khloe….. Khloe has too much to offer and you are not worthy of it. Someone else needs to sweep Khloe off her feet and I am sure there are many,” noted another. “You need to leave her alone if you say you respect her. Tired of seeing Khloe been embarrassed because of you.”

Page Six exclusively broke the news at the end of June that Kardashian and Thompson broke up again after Instagram model Sydney Chase claimed during an April interview that she had slept with the NBA star while he was dating KoKo.

“They’re getting along. There is no drama,” a source told us at the time, adding that “everything is amicable, and they are on the same page with co-parenting.”

The former couple share 3-year-old daughter True.

Thompson’s thirst — or desperation — knows no bounds, as he also publicly declared his love for the “Keeping Up With the Kardashians” alum after their split.

“Your love and spirit is contagious to all who’ve met you,” he wrote in a birthday tribute to her in June. “Thank you for always being there for me and putting our family first. I love you so much. Have an amazing day.”
