While sightseeing around Paris with Lindsay Lohan, Samantha Ronson has been spotted wearing a very conspicuous accessory: an apparent hickey.

Witnesses tell E! News that the DJ and longtime LiLo pal has seemed pretty blasé about the giant red mark staining her neck.

“She could have covered it up and hid it with a scarf or something but obviously felt no need to," the source says.

Which makes us wonder: Is that a hickey? A blow-dart welt? A troublesome rash? What do you think?
