Oh, to be young and in love! Kylie Jenner and Jaden Smith were spotted holding hands (and running for the hills) in Calabasas, Calif. on Monday, Sept. 30. Trying to sneak away from photographers, the couple of seven months hustled their way into a movie theatre to meet up with the reality star's dad Bruce Jenner, step-brother Brody Jenner and his girlfriend Bryana Holly.

Holding on tight, the After Earth actor led the way jokingly screaming while the dark-haired beauty smiled. The Keeping Up With the Kardashians star was later seen leaving the theater wearing some of Smith's clothes.

Us Weekly first exclusively reported that Jenner, 16, and Smith, 15, began dating in March after being "friends forever." Since then, the couple has been photographed out on a lunch date (with Will Smith's son dressed in an "Iron Man" suit!) and celebrating the 4th of July holiday together. In mid-August, Smith was one of many famous faces to attend Jenner's big Sweet 16 birthday blowout at the AT&T center in L.A.

The two lovebirds may have tried keeping a low-profile in front of the paparazzi, but they've done nothing of the sort when it comes to social media. In July, Jenner wrote a heartfelt note to her beau via Instagram to celebrate his 15th birthday. "Although we can't remember exactly when we met, I couldn't be more grateful that we did," she wrote. "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." 

Three months earlier, the Karate Kid star briefly opened up about their relationship to Wonderland magazine. "She's one of my best friends. It's pretty awesome," he said in its May issue.
