If you don't know who Jodie Sweetin is, that just proves exactly how weird this story is. Why is Miley Cyrus, an A-list celebrity, using her social media dominance to take cheap shots at a D-list celebrity? Only Miley's therapist could answer that question, and that person must be very, very busy.

Jodie Sweetin is best remembered for her role as Stephanie Tanner on Full House, and its recent revival, Fuller House. She's also known for having serious problems with addiction, but everyone knows those are all in her past. Everyone except Miley Cyrus, who, on Saturday, chose to post some truly embarrassing pictures of Sweetin in her party days to Instagram.
