Who’s the bigger star?

It should be an easy answer but Tyga did not feel so, and the constant quibbling over scheduling sent their relationship down the drain.

Tyga and Kylie Jenner recently called time on their relationship, and it was so abrupt the reason has not been deciphered yet, according to Tyga anyway.

Whilst it was initially thought infidelity on Tyga’s path torpedoed the relationship, the rapper’s camp says something different.

No worries, it seems Kylie has already moved on, and Tyga apparently is going to write a tell-all book revealing all the secrets of the Kardashians. So win-win.

Read TMZ’s report on why Kylie Jenner and Tyga broke up below.

Kylie and Tyga could not co-exist because their relationship became an unrelenting test of who was more important … at least that’s the way Tyga sees it.

Sources connected with Tyga tell us, he was battling Kylie almost daily over who should kowtow to who when there was a scheduling conflict. They were fighting over which events they’d attend together, which required one of them to scrap their plans.

Tyga is telling friends the Kardashians fueled the conflict because Kylie would complain about him and the family would stoke the coals by telling her that her career was far more important than his.

Tyga’s people say this did not come to a head Thursday … it’s been brewing for weeks.

Apparently, the Kardashians don’t see it the same way … our K sources say Tyga did something to trigger the breakup, and Kylie’s the one who pulled the plug.
