Doesn't he know about Snapchat? And more importantly, who is receiving this bootilicious snap?

Last night Marc Jacobs uploaded the above photo to Instagram with the caption “It’s yours to try!” He was clearly talking about his bare butt, and he clearly also intended to send that as a direct message. But who was getting the gift of MJ's tush? And the tip of his penis, for that matter...

Marc and his porn star beau Harry Louis split in October of 2013, and prior to that he was married to longtime love Lorenzo Martone. Jacobs and Martone were seen together in December of 2013 and again last Christmas in St. Barth, but they haven't officially gotten back together.

The 52-year-old fashion designer quickly deleted the photo from his Instagram account, and he hasn't commented on the matter.
