Jaden Smith and Kylie Jenner Dating? [PHOTO]: 'After Earth' Star Calls Kardashians' Youngest Sister 'Best Friend,' Rap Lyrics Hint at 2013 Romance

Early last month, the 14-year-old son of Will Smith, Jaden, and the 15-year-old youngest half-sister of Kim Kardashian, Kylie Jenner, had the media bussing about a possible romance when the two were spotted in London together. Though neither of them has officially confirmed the relationship, a recent interview in Britain's Wonderland magazine has the Karate Kid star opening up about his relationship with the reality star.

"I was in L.A., 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 said. "She's one of my best friends. It's pretty awesome."

The young movie and music star has been keeping busy. He is set to star in After Earth opposite his father Will. The film is pretty much about what the title suggests and is directed by M. Night Shyamalan. Jaden also has a rap career and one new song might be giving us a hint about his love life. In the song "Know Why," Jaden raps the lyrics:

"And my mom says you couldn't come over / Didn't really care when you pulled up in the rover / Said that I should wait 'til I got older / But love is a war and maybe I'm your soldier / Swag"

Kylie has been pretty busy as well. The 15-year-old has already made her way into the fashion world with her sister Kendall. Together, the two work with Pacific Sunwear (PacSun) and have their own line of clothing with the company: "Kendall and Kylie."

Earlier this week, Kylie posted the following tweet on her Twitter account, showing a picture of her and her sister in their some samples of their clothing brand:
