Kristen Stewart & Nicholas Hoult Dating? Sorry Robert Pattinson & Jennifer Lawrence, 'Equals' Stars Share Romance With 'Intimate' Belly Button Piercing!? [Instagram VIDEO]

Kristen Stewart's no longer dating on-and-off again "Twilight" beau, Robert Pattinson. And rumors suggest that Jennifer Lawrence's Hollywood "ego" is too much for Nicholas Hoult to handle, so they recently broke-up, too. So - does that mean the "Equals" co-stars are getting a bit intimate?

K-Stew and the "Warm Bodies" actor star as lovers in the upcoming 2015 drama/sci-fi flick. But are the two taking their romance OFF screen, also?

The 24-year-old starlet and J-Law's ex have been spending ample time together lately. Is their friendship strictly professional? Maybe, maybe not...

On Sunday (August 3), Hoult shared this rather bizarre video on Instagram - of a "mystery" girl getting her belly button pierced!

itsnicholashoult: "Starting the Sunday with piercings."

Did he share this intimate moment with the "SWATH" beauty? The chick in the short clip isn't identified, but according to HollywoodLife.com, she's wearing a similar white tank top and cropped jean shorts that Stewart was spotted flaunting that same day:

Interesting...

Hoult and Stewart are definitely enjoying some wild and fun adventures overseas together - but are they actually dating?

Stay tuned...
