Ciara assaulted by prankster during Paris Fashion Week...

Ukrainian prankster Vitalii Sediuk strikes again at Paris Fashion Week and Ciara is his latest victim.

An unsuspecting Ciara was posing for pictures at the Valentino show when Sediuk crept up from behind, tore off his coat and revealed a thong. He coddled her and attempted to pose with her, but the singer's bodyguard wasn't having any of it, and rightfully so.

Sediuk made headlines last week when he attacked Kim Kardashian at the Balmain show. Paris cops are refusing to take action for his latest antics. Sediuk's long history of pranks extends to kissing Will Smith at the premiere of Men in Black 3 in Moscow, and rushing onto the stage during Adele’s Grammy acceptance speech last year. He was also arrested after breaking Brad Pitt’s glasses at the premiere of Maleficent, which resulted in him being banned from attending any red carpet events in the States. 

This guy is just asking to get his ass whooped. I don't understand how his "pranks" are legal, especially this one. His junk is digging into her. It's sexual harassment. How is this not worthy of arrest? Watch all the action unfold, below.
