• Missy Elliott has Graves’ disease. The rapper told People the autoimmune ailment made it difficult to do basic everyday tasks, and is the reason she’s kept a low profile in recent years.

• Justin Bieber was knocked to the ground in front of hundreds of fans when an unidentified man jumped a barricade and attacked him outside of a promotional appearance in downtown Manhattan Thursday. WABC reports the singer, 17, was not injured. The 47-year-old man was cited for disorderly conduct, reports AP. Update, 9 p.m.: Turns out it was all a big “misunderstanding,” says Bieber’s rep. The AP reports that the man was a security guard who was hustling to protect the singer from a surging crowd and then disobeyed orders from police who didn’t know he was part of the Bieber team. So feel free to pretend you never spent any time on this saga.
