Tyga previously faced a lot of allegations, and from numerous accusations. Part of it was that he also been judged for dating a minor teen star. Although he's been controversial lately, the issues seem to be not affecting the Kardashian family, especially Kylie Jenner's older sister Khloe Kardashian.

After Khloe Kardashian bravely defended the relationship of Tyga, who is 25 and Kylie Jenner, the controversial rapper was reportedly grateful for the comments made by Khloe, according to Hollywood Life.

A source told the Hollywood Life that Tyga called Khloe right away after he read the article, the rapper was very grateful for Khloe defended his relationship with Kylie over the young love issue.

An insider said, "He called Khloe once he read the article to express his gratitude. He told her 'thank you, sis, good looking out. That's what's family's for." Khloe told him it wasn't a problem.

Adding that "she already thinks of him as family."

In a new spread for Complex magazine, where the 'Keeping Up With The Kardashians' star shows off her bootylicious, she says "Kylie is not a normal 17 year old" kid. Unlike any youngster, Kylie is already doing mature things. So, Kylie having a relationship with an older guy for her age is not a big deal for her.

"Kylie is not a normal 17-year-old," said Khloe. "You're not gonna say, 'Hey, so what are you doing this weekend?' and have her say, 'Having a slumber party at my girlfriend's' or 'Going to prom.' That's not what Kylie does. Kylie is taking business meetings and bought her first house, or she's going on a private place with Karl Lagerfeld to take a meeting.

Further adding that Kylie's case is rare, so her current situation should be treated differently, she said,  "It's a rare circumstance, so let's treat this as a special case."
