Kylie Jenner couldn't help but gush about her boyfriend Tyga in a recent livestream with fans. The 18-year-old reality star and the 25-year-old rapper surprised fans with an impromptu Q&A session on her app where they dished on how they make their relationship work.

According to The Mirror, at one point Jenner revealed what attracted her to the rapper.

“What I love about you is that you’re funny, and you make me laugh," Jenner said. "And that you motivate me.” 

The "Stimulated" rapper said he was a little nervous about doing the livestream, but told Jenner that he likes how she never has any "negative energy" around her.

"You're always fun and always smiling," Tyga explained.

People magazine reported that the pair, who finally went public with their romance in August following Jenner's 18th birthday, also revealed how they deal with the negative attention their relationship gets.

"You just have to look at the fun things in life and be happy," Tyga said. “Because nine times out 10 most of the stuff people feed into the world about you is negative and false anyway."

He added, "As long as you know yourself and you got good people around you and you passionate about what you do, that's all that matters because at the end of the day, you go to sleep with the people you love, you wake up with the people you love and you spend your time with the people you love."

A few other surprises Jenner and Tyga revealed to fans are that they rarely argue with each other and they love to go out on dinner dates. The "Keeping Up With the Kardashians" star jokingly complained that all their outings has caused her to gain "15 pounds," but Tyga didn't seem to mind.

“That’s good man,” the rapper told his girlfriend. “You gotta live man… you need junk food, you need stuff like that in your system.” 

As previously reported, Jenner and Tyga sparked engagement rumors last month when the rapper said the word “fiancée” in a Snapchat video with her. Jenner, however, dismissed the speculation during a livestream on her app with big sister Kim Kardashian, saying that Tyga was making fun of an interview rapper Logic did.
