Vitalii Sediuk is on a roll with his crazy antics. The celebrity-obsessed Ukrainian journalist reportedly jumped on Ciara during a Paris Fashion Week event on Tuesday, Sept 30.

And this time, the prankster was wearing, well, very little.

According to E! News, singer Ciara was attending a Valentino show at Paris Fashion Week when Sediuk ambushed her as she posed for a group of photographers.

As Sediuk gave the music star an unwanted hug, he stripped down to a black thong and gold sequined top.

Ciara appeared visibly startled but reportedly tried to mitigate the situation by remaining calm. Meanwhile, Sediuk smiled for the cameras.

This is the third time that 25-year-old Sediuk has approached a celebrity during Paris Fashion Week.

The notorious prankster dove at Kim Kardashian as she exited a car on he way to a Balmain fashion show.

Kardashian, who was with her husband Kanye West and mother Kris Jenner at the time, struggled to get away from Sediuk as he held onto her legs. Security guards quickly pulled the culprit away but Kardashian appeared shaken.

Sediuk has made a name for himself attacking stars on the red carpet in what he deems harmless acts.

"The prank with Kim was my protest that US banned me from entering the country," Sediuk said in a statement to E! News. "I hope Kim is ok and won't be mad at me as I didn't mean any harm. Kanye is one lucky man as Kim is a Goddess!"  

The former reporter allegedly attempted to approach Kardashian again last week as she dined with her husband at Hotel Costes in Paris.

This past summer, Sediuk crawled under America Ferrera's dress while she walked the red carpet at the Cannes Film Festival. He also allegedly punched Brad Pitt as the actor attended the premiere of his wife Angelina Jolie's film "Maleficent."

Let's hope Paris Fashion Week amps up their security team.
