A scantily-clad pitch invader halted the the Champions League final between Liverpool and Tottenham in the first half.
The blonde woman sprinted across the pitch wearing a revealing black leotard emblazoned with the phrase "Vitaly Uncensored".
She was spotted running with her hands in the air before being caught by stewards and escorted from the field after the referee had been forced to stop play.
The woman is believed to be Kinsey Wolanski, the girlfriend of the Youtube prankster Vitaly Zdorovetskiy, who invaded the 2014 World Cup Final, and is banned from major sporting events for his antics.
But fans were left asking one question - who are "Vitaly Uncensored", the group seemingly behind the interruption?
The adult website claims to undertake "wild pranks" of a sexual nature with "no rules".
A search of their activities showed a number of x-rated pranks in public places featuring a variety of women.
Wolanski boasts over 300,000 Instagram followers, regularly posting pictures of herself showing off her figure.
The Vitaly Uncensored YouTube channel, which has over 1.6billion views, is run by her boyfriend and the pair regularly feature.
Vitaly Zdorovetskiy, better known by his YouTube name VitalyzdTv, was previously a porn actor for Bang Bros in around 2011.
It is not the first time a huge game of this magnitude has been disrupted by a pitch invader, after members of Pussy Riot crashed last year's World Cup Final.
The Russian protest-art group took responsibility in the immediate aftermath of the France vs Croatia showpiece being stopped.
The incident cam after a ridiculous Champions League campaign got off to a fitting start in Madrid.
Sadio Mane's attempt at a cross was adjudged to have been handled by Moussa Sissoko by referee Damir Skomina, who pointed to the spot.
There was a substantial wait as the video assistant referee checked the decision, but Salah kept his nerve and buried the spot-kick.
Spurs settled after the worst possible start, and both sides quickly got back into their rhythm after the delay due to the pitch invader.
