We had already closed up shop for the weekend when these photos of Paris Hilton (or someone who looks a lot like her in three-quarter rear profile) and her nether regions appeared in our inbox, but in a way we're glad to be posting them now instead of last Friday night. After all, what better way is there to start your week than by saying hello to an old friend?

Photos (including a terrifyingly high-res closeup!) after the jump.
