Things aren't looking good for Kylie Jenner and boyfriend Tyga!
The 25-year-old rapper reportedly called up his ex-fiancée (and baby mama) Blac Chyna to complain about the 18-year-old.
"[He] called Blac Chyna because he’s been bored out of his mind and [he’s been] having problems with Kylie," a source tells HollywoodLife.com. "[Kylie] sometimes makes him feel like scum because of where he’s at in his career."
And that's not the only thing! According to the source, Tyga thinks the reality star's ego is "way out of control." But don't assume that the "Stimulated" singer is hooking up with his ex, whom he has a two-year-old son with, behind Kylie's back!

"[Tyga] didn’t talk sexual with Blac. He was just venting to her, and she listened," the source reveals.
