Red carpet official! Kylie Jenner and boyfriend Jaden Smith attended the Hollywood premiere of 

Ender's Game, starring Harrison Ford, together on Monday, Oct. 28. Not hiding their romance any longer, the young couple shared a big hug in front of photographers while walking the carpet.

An eyewitness tells Us Weekly that Jenner, 16, and Smith, 15, both looked relaxed while posing for pictures with their arms around each other. The Keeping Up With the Kardashians star dressed up for the date night in a black printed T-shirt, mauve skirt and gladiator heels. Will Smith's actor son rocked a futuristic-looking white-and-black shirt and shorts with mismatched sneakers.

Us exclusively reported in March that the young stars were dating. A source told Us at the time, "It's new, but they've been friends forever." Since then, their love has only appeared to blossom. In July, Jenner wrote a heartfelt note to her boyfriend 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. "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."

After her movie premiere date with Smith on Monday, Jenner retweeted a telling quote: "I hope you fall in love with someone who makes you question why you ever thought you would be better off alone."

While Jenner was on her date with Smith, many of her family members attended soon-to-be brother-in-law Kanye West's Yeezus tour show at the Staples Center in L.A. In addition to Kim Kardashian, Kris Jenner, Rob Kardashian and Kendall Jenner attending, Khloe Kardashian and her estranged husband, Lamar Odom, also reunited at the show.
