Kylie Jenner and Tyga split after falling out over her friendship with Rob Kardashian’s fiancee Blac Chyna, according to reports.
Blac is Tyga’s ex and the mother of his child King Cairo from their relationship before he got involved with Kylie.
Now that Blac is engaged and expecting a child with Kylie’s half-brother Rob, the reality star has made an effort to get along with the model.
But the friendship apparently did not sit well with Tyga, who was spotted dining with a mystery model and his mum on America’s Mother’s Day.
Tyga is said to have branded Kylie a "fake bitch", before ending their two-year romance.
A source told Radar: "Tyga thinks that Kylie is a total sell out and he told her that he did not even know who she was anymore.
"The fact that Kylie totally went back on her word put Tyga over the edge."
We have contacted representatives for both Tyga and Kylie for comment.
Kylie and Tyga are not said to have parted on good terms and arrived separately at the Met Ball in New York last week.
Model Kylie was reportedly furious Tyga still attended as she thought he was only invited because of her.
Last night, Tyga broke his silence after news of the couple’s split broke.
He told E! News: "I’m good, you know? Just another day and working hard and trying to get to that next level and achieve big things and evolve."
