Rumors suggest that Jennifer Lawrence's ex showed support for the 24-year-old "Twilight" sweetheart at the recent NYC premiere of her new independent drama, "Camp X-Ray." But he was very discreet about it - according to PopSugar.com, the 24-year-old "Warm Bodies" actor alledegy "snuck into" the screening's entrance while K-Stew walked the red carpet with co-star, Peyman Moaadi.

Side note - Stewart looked absolutely stunning! No wonder why Hoult might have a little "crush." Check out some candid red carpet snapshots here.

Apparently, Hoult avoided the crowd and didn't pose for any autographs. The popular gossip webloid claims that he attended the viewing relatively "unnoticed."

The "X-Men: Days Of Future Past" star is also in NYC promoting his own new flick, "Young Ones."

Do MstarsNews readers think they'd make a cute couple, or are the two young Hollywood heartthrobs just having some noncommittal fun together while filming?

The "SWATH" beauty was recently spotted cruising around LA with another "mystery" man, but it remains unconfirmed if this guy's the new romance in her life.

But it might be time to officially move-on... Stewart's ex-boyfriend Robert Pattinson is definitely heating things up with new rumored girlfriend, FKA Twigs...

The 2014 Sundance Film Festival hit will premiere in theaters on October 17:
