red carpet catching fire Kylie Jenner

It wasn't just about Jennifer Lawrence and her see-through Dior dress -- there were plenty of other sexy starlets at the Los Angeles premiere of The Hunger Games: Catching Fire, even if they weren't actually in the film!

Kylie Jenner walked the carpet in a tight grey dress, and from the ankles up we're loving her look! (C'mon ... boots with a sexy dress? Is she taking fashion advice from Kimye?!) Kylie may not have any legit acting credits to her name, but she has long been a big fan of the Hunger Games -- in fact, in 2012 she revealed that the sci-fi novel she's writing with sister Kendall is inspired by the series. We can't WAIT to read that...

Ashlee Simpson and Evan Ross made yet another appearance last night, and the singer/actress wore a long black Amanda Wakeley gown and her blonde locks swept to the side:

And it sounds like these two are ready to take things to the next level! Evan chatted with omg! INSIDER about his relationship with Ash and said, "It's amazing. I'm so in love. We [have] amazing things going on and we inspire each other…She [is] the one." Wow! And not only that, but when asked if he plans to marry his lady love, Evan exclaimed, "For sure!"
