Kylie Jenner and Tyga are allegedly having more problems.

According to a report from Hollywood Life, the "Stimulated" rapper has become too busy with his career to spend enough time with his reality star girlfriend.

The 25-year-old hiphop star is said to be extremely focused on his music, which has caused his 18-year-old girlfriend to be doubtful.

"She hates it when she and Tyga aren't together," an insider shared about Kylie Jenner.

"He's been busy, locking himself in the studio and barely giving her any of his free time in the past month, so she was feeling a little left out."

"To make sure she'd get some time with him, Kylie would go visit at the studio, but he's so into his work and she feels bad distracting him," the insider revealed.

The youngest Kardashian-Jenner sister supposedly understands that Tyga wants to do well in music to impress people, specifically her famous reality TV family.

"Kylie Jenner knows that Tyga is always trying to prove himself," an insider said.

"She doesn't want to get in the way of his creative process, but she can't help her feelings and can't help missing him."

Kylie Jenner even hinted about her relationship problems with Tyga in her recent cover feature for Elle Canada.

In the interview, the youngest daughter of Caitlyn Jenner and "momager" Kris Jenner admitted that she does not like to talk about her issues with her rapper beau.

"I do think that if you let people in too deep, it gets hard-your fans get too invested, and then they know when you break up and make up," she said.

"I don't want people to know every time we fight or break up, so I'd rather keep some things private."

Aside from Kylie Jenner and Tyga disagreeing over the latter's hectic rap career, sources also claim that the rapper's ex-girlfriend, Blac Chyna, is still causing problems between the controversial couple.

The sexy starlet is also the mother of Tyga's two-year-old son, King Cairo.

"Kylie and Tyga certainly have their share of problems, most of them stemming from Blac Chyna," said a source.

"Kylie flat-out doesn't like her. She thinks Blac still has a thing for Tyga and that bothers her."

"But Kylie gets it though, that Blac and Tyga have a child together so for that reason, the two of them must communicate," the source added.
