Kylie Jenner was all support for her rumored boyfriend Tyga during his concert at The Forum in Los Angeles on Sunday evening. The 17-year-old even wore matching necklaces with the 25-year-old rapper.

"Kylie Jenner brought out one of her more extreme looks when she stepped out in a pair of hard-to-miss lace up boots that went above her knees," Daily Mail reported. "The footwear gave the 17-year-old a whole new image."

Also accompanying her sister was Khloe Kardashian, who figured in the tabloids lately for her alleged liaisons with both her exes, French Montana and Lamar Odom.

Tyga and Kylie Jenner have been denying that they are in any type of romantic relationship.

In an interview with The Breakfast Club, the rapper tried to clear the air about his rumored relationship with Kylie Jenner.

"No, I'm not dating Kylie. I wanna be clear to everybody, I didn't leave my family to be with Kylie. That's ridiculous," he said. "Me and [ex Blac] Chyna, we broke up almost close to a year [ago] now, because of the decision we made, and things in our relationship that were not going right, [we] decided to split to raise an emotionally stable kid."

However, he did compliment Kylie Jenner for possessing the "maturity and mentality ... different than a lot of people."

But Daily Mail noted that Tyga would deny any romantic relationship with Kylie Jenner "because she is a minor."

"She will not turn 18-years-old until August 10," it said. "Also, he has a child with his ex Black Chyna."

For her part, Kylie Jenner did not address directly the Tyga rumors in an interview with Fault magazine but she said a woman should not be defined by her man.

"I don't think I need a significant other to be happy because I always like to find that for myself," she said. "But I think that it makes me a lot happier when I'm sharing my life with somebody."
