Selena Gomez is trying on a new shade of mystery. In a June 3 Instagram post from London, the actor gave fans a behind-the-scenes look at Only Murders in the Building season six, including what appears to be a wavy auburn wig that has already started doing its own press tour.

Selena Gomez shows off an auburn look in London

Gomez, 33, shared a carousel documenting her time across the pond as she films the Hulu comedy with Steve Martin and Martin Short. The red-haired reveal comes near the end of the post, where Gomez is seen looking up at the camera with auburn waves framing her face.

Another clip shows her lying in bed while wearing the same hairpiece and quietly admiring the change. So yes, assume it is a wig — though on this show, a hair color can probably count as a clue until proven otherwise.
