Earlier today we reported that something was amiss between Kylie Jenner and Tyga, after she very notably skipped his birthday celebrations.

Now, it's been revealed that the pair have in fact officially split up, with Kylie pulling the plug on things just yesterday.

The reality star dumped her boyfriend of almost two years – on his birthday, no less – over "something he did," sources tell TMZ.

What exactly went down between the couple is unclear, but it's also been suggested that the decision was made due to "pressure from the Kardashians."

After spending almost a week apart while Kylie visited Australia on a press tour for her new clothing range with big sister Kendall, the couple parted ways yesterday.

And at a dinner with friends last night, the teen apparently had some "harsh" words to say about her ex.

While some sources have said that things are over for good, another insists it's just a short term thing and that Tyga is doing everything he can to change his lady's mind.

"They are on a break," an insider tells E! News.

"They were just a week or so ago talking about ‘ever after' and things got messy this past week.

"Kylie wants time to just be by herself and do her. Tyga is not giving up as that's his one and only lady."

Just yesterday SHEmazing! reported that Tyga was facing some serious legal trouble as well as being in debt to the tune of €55k – and it seems Kylie simply might have had enough of her boyfriend's questionable behaviour.

The rapper is reportedly "devastated" by the turn of events and denies "doing anything" to warrant a break-up. 

He certainly didn't appear too devastated last night though, as he celebrated his 26th birthday with friends including A$AP Rocky, Leonardo DiCaprio, Rod Stewart and Wiz Khalifa at 1 OAK in LA.

Far from begging Kylie to take him back, the father-of-one spent the night posting videos to Snapchat of his birthday shenanigans.

Somehow we doubt that went down too well with the Kardashian-Jenner clan…
