According to Life & Style magazine on Wednesday, Kylie might be a little more invested in the relationship than Tyga is.

A source told the site, "Tyga likes to have his cake and eat it too when it comes to women. When Kylie's around, he acts like the perfect boyfriend, but he definitely has some ladies on the side."

The insider added, "Its only a matter of time before she finds out the truth."

Meanwhile, there's a rumor that says Tyga is encouraging Kylie to get a butt lift.

According to OK! Magazine recently, Tyga is so obsessed with Kim Kardashian's curves that he wants his girlfriend Kylie to get a Brazilian Butt Lift.

A source told the site, "Tyga is playing a dangerous game with a very young and easily influenced girl. Kylie already has deep-rooted insecurities because of her upbringing, and it's no surprise she's hooked on surgery, so encouraging her to do something drastic like a butt job is madness."

So far, Kylie herself has not responded to any of the rumors.
