A man who streaked the Eurovision half-time concert wearing an Australian flag isn't an Aussie after all.
The man's been unmasked as Hollywood 'prankster' Vitalii Sediuk, a Ukranian man who has made headlines before for attacking a string of celebrities.
Sporting stubbies and an Australian flag, he ran onto the stage while last year's winner, Ukraine singer Jamala, performed in front of her home-country crowd. Standing in front of the singer, he whipped down his pants and wiggled his bare bottom, before being tackled by security.
He's been banned from all red-carpet events in Los Angeles and narrowly avoided jail after jumping on stage during Adele's Grammy acceptance speech in 2013, accepting the award on her behalf.
