Kylie Jenner and rumored boyfriend Jaden Smith both attended the Hunger Games: Catching Fire Los Angeles premiere on Monday.

The Keeping Up With The Kardashians reportedly upstaged the film's lead star Jennifer Lawrence when she arrived wearing a form-fitting long grey dress with black pointy-toe ankle boots.

The 16-year-old looked older than her years sporting dark lipstick and dark hair accented with a honey blonde color at the tip. She resembled her older sister Kim Kardashian who has been seen with similar locks and dark vamp lipstick, following the June birth of her first child North West.

Jenner's rumored boyfriend also attended the premiere for the sequel that will arrive in theaters on Friday. Despite hugging up on the red carpet for the Ender's Game premiere in New York City a few weeks ago, the rumored couple walked Monday's red carpet event separately. Smith walked with his younger sister Willow Smith.

Jenner also didn't mention Smith in social media on Monday. On Instagram she simply wrote, "fun night with jordy. #hungergames"

The alleged teen couple was first seen together in London in early March. Eyewitnesses told Mail Online they spotted Jenner and Smith kissing during their dinner date at Sophie's Steak House in Covent Garden on March 1. A source close to Jenner claims that the young stars are in fact an item, telling Us Weekly, "They're dating. It's new, but they've been friends forever."
