Kristen Stewart & Nicholas Hoult 'Romance' PHOTOS: Robert Pattinson's Ex Flaunts Tomboy Look For 'Equals' Movie, Jennifer Lawrence Jealous?

Kristen Stewart stars alongside Nicholas Hoult in the upcoming drama/sci-fi flick, "Equals." The former "Twilight" starlet flaunts a very tough, tomboy-esque look for the new film.

UPDATE: Robert Pattinson vs. Nicholas Hoult, Jennifer Lawrence's 'Ex' Steals Kristen Stewart AND Riley Keough? 'Equals' Actor Flirts, 'Twilight' Hottie Jealous?

K-Stew and Jennifer Lawrence's boyfriend are currently in Japan promoting "Equals" (set to hit theaters sometime in 2015). The 24-year-old actress sported a rather casual (yet somewhat sloppy) look at a recent press conference in Tokyo. Still, she manages to somehow look completely stunning! Check out some snapshots via the Daily Mail.

Rumors initially suggested that J-Law was "jealous" of Stewart, knowing about her rather flirtatious tendancies with co-workers on AND off-screen. The "Hunger Games" beauty quickly laughed-off such gossip, but does she really have something to worry about?

Robert Pattinson's ex and 24-year-old Hoult were recently spotted on a "dinner date" together - but was it romantic at all? The two grabbed some sushi on Thursday (July 31), and tried escaping attention from the paparazzi. These photos later went viral on Twitter:

Just a strictly-buisness friendship, or is something else going on...
