Kylie Jenner just realized that her boyfriend Tyga will be on overseas tour soon and she is worried that her man is going to end up cheating on her.

HollywoodLife.com reported that the pair's relationship has been rocky these past few weeks. As a matter of fact, a source revealed to the publication that the two has been fighting a lot lately, adding, "but the last think Kylie wants is for Tyga to leave on an angry note."

"Kylie's calming her ass down. The last thing she wants is for Tyga to go on his Australia - New Zealand in a week mad at her. She doesn't want Tyga to get out there, lose his mind and cheat on her with another woman," the insider divulged to the media outlet. "That would really f--- things up in their relationship and at the end of the day, Kylie doesn't want that."

"She wants to join him but at this point, she doesn't know if her schedule will allow that. So in the meantime, she's trying to butter him up. Kylie knows Tyga loves to shop, especially for shoes, and that's why she took him to the mall yesterday," the insider explained. "She chauffeured him in her Rolls and bought him just about everything he asked for - mostly shoes and a few jerseys. Surely, Tyga can do all that for himself but Kylie was trying to be extra nice and make things as perfect as can be before he leaves."
