They’re over…again. But this time, it’s for real, supposedly. Allegedly. Deets inside on Tyga and Kylie Jenner‘s breakup….

Reports just broke that Tyga and 18-year-old girlfriend Kylie Jenner are officially over. This comes days after Tyga congratulated his ex-fiance Blac Chyna on her and Rob Kardashian‘s baby on the way.

Kylie and her sister Khloe Kardashian have been Snapchatting each other all night talking about Kylie’s “great qualities” and explaining who she really is. We wouldn’t be surprised if this was a tactic to pre-empt any negative stories that Tyga or others may unveil about her in the coming days.

As for WHY they’ve broken this time, who knows. But TMZ claims Tyga already has another model chick tagging along with him these days who showed up to brunch with him and his mom on Mother’s Day.

The site also claims Kylie is pissed Tyga went to the MET Ball even though he was only invited because of her:

Sources connected to the former couple tell TMZ … it happened days before the Met Ball last week. They were both at the gala, but they did not walk the red carpet together, and that was her decision.

…

We also know this … the breakup was acrimonious. We’re told Kylie was bent out of shape that Tyga had the nerve to go to the Met Ball. He was only invited because of her, and she’s mad at herself that she didn’t think to have him made persona non grata.

Y’all know that family does not like when you and your blackness do what you please instead of catering to their demands. Ask Blac Chyna, Lamar Odom, Kris Humphries, and others. “Poor Baby!!”
