It’s pretty clear that it would be tough for Tyga and Kylie Jenner to make a clean break after their split (after all, her brother is engaged to the mother of his child). But now it looks like authorities might be getting involved in their breakup.

Apparently Tyga is doing a bit too much after he and Jenner reportedly agreed to go their separate ways.

“Kylie has threatened Tyga with a restraining order since he refuses to stop calling, texting, and emailing her,” an insider told Radar Online Friday. They added that it was first Kris Jenner’s idea. But Kylie “is starting to come [around],” as well.

Word is the two split because it was just too awkward for them to stay together now that Rob Kardashiand and Blac Chyna are not only engaged, but expecting their first child together. It’s no secret this could be a little confusing; especially for the children involved. But Tyga doesn’t seem to be too bothered.

“Tyga’s absolutely out of control and goes from begging her to take him back to leaving angry four-letter messages for her if she doesn’t pick up,” the source continued. “He’s so desperate right now and needs serious money fast or he’s going to go under – she was his major cause of income and now that’s gone. Kris is worried he’s capable of anything.”

But if Kylie does decide to go through with it, Tyga shouldn’t be shocked.

“Kylie’s warned Tyga it’s coming if he doesn’t leave her alone.”
