Not so fast!

The rumor mill went into overdrive on Tuesday when TMZ reported Justin Bieber and Hailee Steinfeld were dating, but the thing is they're not! The actress cleared up the confusion during a SiriusXM’s Morning Mash Up radio interview on Wednesday.

"I don't know why people make such a big deal. We're friends. We've been friends for years," she explained.

The chatter got started after they photographed hanging out in NYC after the Met Gala, a month after JB was caught Facetiming the Oscar nominee.

In reality, she has been dating boyfriend Cameron Smoller since late last year. If we were him, though, we wouldn't want our chick kicking it with The Biebs! She might catch Bieber fever!
