Are Logan and Demi dating?

Demi and BTR's Logan have been just buds for a long time, but when Demi showed up to the premiere of Big Time Movie in NYC, we couldn't help but notice that they were acting super close. Could they be more than friends now? "We don't want to answer at this time," Logan's rep tells M exclusively. Hmmm, something might be brewing- we'll keep you posted!
