Just before the 20 minute mark, with Liverpool leading Spurs 1-0, a woman in a swimsuit ran onto the pitch of Wanda Metropolitano.
Security soon ushered her off the field, and the fun stopped, and play was resumed.
But as it turns out, her busty outfit with and advert on it was more revealing as it was initially suggested.
The scantily-clad pitch invader, named Kinsey Wolanski, promoted X-rated PORN website Vitaly Uncensored that vows ‘wild pranks, t*** and a**, no rules’.
It was launched by Vitaly Zdorovetskiy, a Russian-American YouTube personality.
In a video promoting the site, he promises “pranks on another level, something you’ve never seen before, way to explicit for YouTube.”
He continues: “When the censors tell me ‘no’, I say ‘f*** them’.”
Zdorovetskiy runs a popular prank channel VitalyzdTv, whose videos have reached over 1.65 billion views and over 9.9 million subscribers as of May 2019.
In fact, the mystery blonde bombshell – who was cheered for her stunt by the Wanda Metropolitano crowd – is the YouTuber’s partner.
Zdorovetskiy wrote on Instagram following her run: “My f***ing baby girl just streaked Champions League Final, so proud of you, you’re my everything.”
