It's official: 15-year-old Jaden Smith, son of Will and Jada Pinkett Smith, has been dating 16-year-old Kardashian family clan member, Kylie Jenner for seven months, and it looks like it may be love! The two recently attended the "Ender's Game" premiere together in Hollywood and got cozy on the red carpet, US Weekly reports.

With their arms around each other, the young stars looked relaxed posing for pictures, as an eyewitness told the gossip magazine, Smith wearing a white-and-black shirt with shorts and mismatched sneakers with fashionable Jenner rocked a black graphic tee, mauve skirt and gladiator heels.

"[Their relationship is] new, but they've been friends forever," a source told US Weekly back in March. In July, Jenner wrote her boyfriend a special note in celebration of his 15th birthday.

"Although we can't remember exactly when we met, I couldn't be more grateful that we did," she wrote at the time. "You understand me like not many do and you always know the right time to make me laugh. And no, you haven't failed once to catch me when I attempt to walk or open the door on my every entrance. Happy birthday to my best friend."

As for their relationship, it seems to have grown and developed over time, as just after the premiere yesterday, Jenner retweeted the quote, "I hope you fall in love with someone who makes you question why you ever thought you would be better off alone."

At the premiere, Smith also hung out with his friend Hailee Steinfeld, one of the stars of the new movie. The 17-year-old wore an eye-catching outfit that included a one-shouldered Saint Laurent sweater covered in sparkly red kissy lips tucked into a pair of black trousers and worn with black heels.
