Ben Simmons Kendall Jenner

Tinashe’s brother took aim at NBA rookie Ben Simmons for cheating on his sister with comely model and socialite Kendall Jenner. Tinashe’s brother Kudzai, 19, lashed out at the 21-year-old 76ers star for breaking his sister’s heart.

“Never met you before in my life. days after u break my sis heart u do this,” Kudzai tweeted on Wednesday. “ppl (people) all lied on her talking fake news about my sis doing kardashian s**t u cheat on her [with] a Jenner [crying with laughter emoji].”

When another Twitter user claimed the singer only dated the pro athlete for a month, her brother responded, “They ‘broke up’ sunday my guy.. u literally don’t know anything, stay quiet about this.”

He also told a user that Simmons’ young age is “no f**king excuse for cheating” and concluded his rant by writing, “Sorry for blowing up y’all twitter everyone. it was actually the only way to defend my sister against all this bulls**t.”

Security was tight while Jenner, 22, and Simmons, 21, spent time together last week in Manhattan with a group of friends at a restaurant, a source tells Page Six exclusively.

The 6-foot-10 guard was previously linked to the 25-year-old singer, who still has photos of him on her Instagram page. He has deleted her photos from his page.

Tinashe revealed she was dating Simmons in March, calling him her “little boo thang”, weeks before she told Billboard, “He’s like my full boyfriend, I guess.”
