They haven't even officially confirmed their relationship yet, but it looks as though Kylie Jenner and Tyga might be in some serious trouble. Rumor has it that the rapper recently spent $5,000 on a night out with strippers- with his girlfriend no where in sight.

According to Hollywood Life on Wednesday, Tyga's wild night allegedly happened at a Houston strip club this past week along with a group of friends. Apparently, $8,000 was spent at the club in total, with $5,000 coming from the rapper's own pocket.

Apparently, Tyga spent the night partying with bad boy Chris Brown, who recently broke up with on-again and off-again model, Karrueche Tran.

Just recently, Kylie and Tyga were criticized for their relationship as some are saying that the huge age gap between them is "not normal."

According to Fox News on Tuesday, clinical psychologist Dr. Chloe Carmichael, who specializes in relationship issues, says that Kendall and Tyga have a very little chance of having a successful relationship as they aren't on the same level emotionally.

"Tyga is actually 50 percent older than Kylie, which makes a big difference in terms of development at the age of 17. Kylie is so young that her cerebral cortex is still forming- the cerebral cortex is what helps us to strategize, consider future consequences, and put emotions into context," Carmichael said. "It's unhealthy because Kylie is in a 'one down position' by dating a man whose brain and body are fully formed while she is literally still developing."

Carmichael says that even though Kylie has been exposed to a very mature world, thanks to her older sisters in the Kardashian family, she's still very much a teenager trying to grow up too fast to keep up with everyone around her.
