Notorious celebrity prankster Vitalii Sediuk has struck again — and this time his victim was Justin Timberlake.

The singer and actor was heading into Louis Vuitton’s Paris Fashion Week show with wife Jessica Biel when the man struck, grabbing Justin’s leg in an attempt to knock him down.

Fortunately, security jumped in and got the guy off Justin.

Vitalii has also attacked Gigi HadidLeonardo DiCaprio and Brad Pitt. In 2013, he rushed the stage at the Grammys.
