Justin Timberlake is the latest celebrity to be targeted by self-styled “prankster” Vitalii Sediuk.
The 38-year-old singer was attending the Louis Vuitton Spring Summer 2020 show with his wife Jessica Biel when Sediuk staged his latest stunt.
The 30-year-old joker - whose controversial actions have not always been laughed off - reached out grabbed Timberlake’s leg as he walked past.
Photographs of the incident show Sediuk clinging to Timberlake’s lower leg, before his security stepped in to detach the pair.
A source played down the incident, telling People magazine: “He was not attacked. This is just getting blown way out of proportion.
“Justin’s fine, the guy just touched his leg.”
In the past, Sediuk's pranks have caused chaos with one Cannes Film Festival incident saw him crawl underneath actress America Ferrera's dress.
In 2014, he spent two days in jail after trying to hug Brad Pitt at the Maleficent premiere.
While reaching for an embrace, Sediuk knocked into Pitt and was charged with battery and unlawful activity at a sporting or entertainment event.
He was sentenced to three years of probation.
