Khloe Kardashian Calls Kylie Jenner, Jaden Smith Union 'Sweet'

Khloe Kardashian, the 28-year-old reality television star, is revealing her thoughts about her little sister Kylie Jenner reportedly dating movie star Jaden Smith.

Jenner, 15, and Smith, 14, have sparked speculation that they are dating after being spotted together on a number of recent outings. Now, Kardashian is speaking about the reports.

"I think he's so sweet … but I will also say they're teenagers and I really can't keep teenagers straight," Kardashian told Seacrest on radio station 102.7 KIIS FM. "You just never know. Everything is up and down, but they're definitely best friends."

Although Kardashian did not confirm whether a romance was budding between Smith and her sister, the 28-year-old told Seacrest that she was "kind of obsessed" with the young actor. Smith, the son of actors Will and Jada Pinkett Smith, spoke up about his relationship with Jenner in Wonderland Magazine recently.

The young Smith described appearing on recent outings with Jenner.

"I was in LA, we were all hanging out. Then I went to New York and she came too, and then she came here and surprised me, so that's pretty baller," Smith told the magazine. "She's one of my best friends. It's pretty awesome."

Last month, Jenner, 15, and Smith, 14, were spotted on an outing that was supervised by the Smith patriarch. Smith and Jenner dined at a sushi restaurant in London called Nobu with the 14-year-old's father watching from a safe distance, according to Perez Hilton.

In an interview with the.LIFE Files last year, Smith spoke about how his father's advice has impacted the way that he approaches romantic relationships.

"My dad one time told me, he was like, 'The only time you should lie is when someone's holding a gun to your head and says 'Okay, lie or I'm going to shoot you.' And that really stuck with me," Smith said. "I think about that a lot. I used to not be really honest with girls and then I dropped a song called 'Starry Room' and then I started turning over a new leaf. Now, I'm completely honest with girls all the time and they just get mad at me."
