Kristen Stewart Dating New Boyfriend Amid Robert Pattinson & FKA Twigs Romance? 'Twilight' Starlet Cruises With 'Mystery Man,' NOT Nicholas Hoult, Jealous Revenge?

Things are definitely heating-up between Robert Pattinson and new girlfriend, FKA Twigs. And all the cyber haters can quit it - the "Two Weeks" songstress is happy!

Wonder how that makes Kristen Stewart feel? Especially since her "Twilight" ex-boyfriend continues taking Twigs to several of their former "date spots" throughout LA...

But apparently K-Stew's ready to move on too with a new "mystery" man of her own...

And, no - this time it's not "Equals" co-star, Nicholas Hoult.

Several gossip reports confirm that the 24-year-old "SWATH" starlet was spotted cruising around LA with a male companion riding shotgun. The man's identity remains unknown, X17 simply refers to him as "CJ."

Check out the photos via Daily Mail.

Stewart looked content riding through Hollywood last Thursday (Oct. 2), flaunting a casual white tee-shirt and baseball cap.

The "Camp X-Ray" beauty continues traveling back-and-forth between the States and Japan while filming the sci-fi/romantic drama, "Equals."

Do Mstars fans think Stewart's dating this new guy, or does she have something "secret" going on (both in and out of the studio) with Jennifer Lawrence's ex?

Perhaps she's just trying to keep her mind off of R-Patz's new blossoming romance...

Stay tuned as more details develop! Do Robsten fans still think there's hope at this point?
