Whoa! Selena Gomez was perhaps inspired by boyfriend The Weeknd after he chopped off his famous topiary-inspired 'do and has chopped off her lovely locks into a short, edgy bob. We love it!

All the girls are doing it these days -- if it isn't Kristen Stewart and Cara Delevingne shaving their heads, it's all the other Hollywood beautys ditching the extensions and slicing off the dry ends and ending up with short, healthy, cool hair.

Selena posted some Polaroid snaps on Instagram, on Tuesday, in which she appears to be wearing a white bathrobe with wet hair. The 24-year-old is a spokesperson for Pantene ... could this be a viral campaign for the hair care company? The photo was absent of a caption and some fans are speculating it's a wig. But we say it's the real deal! Stay tuned ...
