Prince Michael "Blanket" Jackson II went to a bar mitzvah at Bagatelle in West Hollywood with a group of friends on Saturday night, and the 14-year-old, who is the youngest son of the late Michael Jackson, was all dressed up in a tux. We're not sure what his curfew is, but is that a yawn we see? It certainly seems like the teen is out a little bit past his bedtime...

Blanket, along with his siblings Paris and Prince, live with their co-guardians, grandma Katherine and cousin Tito in Calabasas, and the identity of his mother is still a mystery. Blanket was just 7 years old at the time of his famous father's death, and while his big sis has gotten most of the media attention over the years, Blanket has been making more and more appearances lately.

Speaking of unsolved mysteries, there was a report that Blanket changed his name to Bigi, but we haven't heard much about it since. “He always thought that the name Blanket sounded so stupid and resented his father for calling him that,” an insider told Radar last year. “Growing up, his school mates have always been slightly mean to him because of their jealousy over who he is and going by Blanket made him a much easier target for ridicule.”
