Kristen Stewart & Nicholas Hoult Together, Forget Robert Pattinson & Jennifer Lawrence? 'Equals' Lovers Share Bizarre ALS Ice Bucket Challenge [WATCH]

Kristen Stewart and Nicholas Hoult are working very closely together for their highly-anticipated upcoming flick, "Equals." Of course, this immediately sparked rumors that the two are actually dating in real life, considering Jennifer Lawrence recently broke things off with her "X-Men" beau. And as most fans already know, K-Stew is no longer with on-and-off again "Twilight" sweetheart, Robert Pattinson.

Stewart and Hoult have yet to confirm or deny such romance buzz, but again, they are spending a LOT of time together (both on and off screen)!

Most recently, the two stars came together in support of a very good cause - the ALS Ice Bucket Challenge.

The 24-year-old actress was recently nominated by Anne Hathaway:

Hoult didn't say much throughout the clip, besides nominating some other celebs including Colin Firth.

So - are the dating rumors true?
