T.I. and Tiny Reunite During Romantic Xscape Performance — One Day Before Rob Kardashian Accuses Them of Having a Threesome With Blac Chyna!

Well, that romantic moment was kinda ruined.

T.I. and his estranged wife, Tameka “Tiny” Harris, reunited at Xscape’s Tuesday, July 4, concert in Detroit. Tiny, 41, serenaded the hip-hop star, 36, and their 14-month-old daughter, Heiress, during a particularly emotional performance of the girl group’s 1995 hit “Do You Want To?”

While Tiny (who sizzled in a sexy, gold mini dress) looked particularly in love with T.I. — she even held his hand at one point! — their sweet interaction was tainted on Wednesday afternoon when Rob Kardashian claimed in an epic social media tirade that the former couple had a threesome with his ex-fiancée, Blac Chyna.

After Rob, 30, attacked Chyna, 29, on Instagram, T.I. chimed in with some advice for the sole male Kardashian.

"Why bring ya business to IG tho?" the “Live Your Life” rapper wrote. "Look, you got worked bro… but at least keep it to yourself, you letting the world know you a duck. I mean a BIG DUCK, a mighty duck, Ronald McDonald the duck, Scrooge McDuck, Howard the Duck, Huey [Dewey] & Lewie… save the #DuckTales. Just hold this L, kiss ya kid & cut ya losses & move on… u got no moves bro.”

This comment prompted Rob to clap back immediately by writing, "Since T.I. wanna chime in on business that don't concern him let's talk about the threesome you had with Chyna and your baby mama Tiny. Don’t speak on my daughter when u having threesomes with young Chy and Tiny… and I put that on my daughter's life since u wanna speak on my daughter.”

The Arthur George sock designer continued, "Damn shame. Chyna told me everything about your threesomes with you and her and Tiny. U got no moves bro… Correction: T.I. paid Chyna to have sex with Tiny and him.”

Prior to their onstage reunion (and Rob’s accusation), Tiny filed for divorce from T.I. for a second time in April because the court failed to serve the rapper with papers after originally filing in December 2016.

Tiny — who also shares kids King, 12, Major Philant, 9, with T.I. — discussed her decision to part ways with the musician during an interview with Wendy Williams earlier this year.

“We just cannot keep it together. I guess, entertainment, life, everything…it’s just a lot. They call him a sex symbol, I guess,” Tiny said, noting that starring on VH1’s T.I. & Tiny: The Family Hustle had a negative impact on their relationship. “[That] did put a little strain on it because it keeps people in your business.”
