Katie McCabe started the party when Arsenal lifted the Women's Champions League trophy for a huge audience of supporters outside the Emirates Stadium.
The Gunners defeated the European giant Barcelona 1-0 on Saturday to win their second Champions League title.
Stina Blackstenius scored the decisive goal only seven minutes after he came from the couch for midfielder Frida Maanum.
Against the expectation, Arsenal lifted the trophy in Estádio José Alvalade in Lisbon.
After partying in Saturday evening – and enjoyed a performance by pop star Jess Glyne in their hotel – the Gunners returned to London the following afternoon.
They spent Sunday evening with parties in Mayfair before they went to the Emirates Stadium on Monday for a trophy lift.
At least 10,000 fans arrived on the ground to view Renee Sleesers and co -parade the silverware.
But it was McCabe who stole the show during the presentation, which was organized by Alex Scott just above the club Megastore.
The defender took the microphone from the arsenal icon before he broke into the song.
McCabe sang singing for people such as Blackstenius, Slesers and Beth Mead before they had a 'Jack Wilshere moment' for the supporters.

Just like the Fan-Favourite midfielder, it did in 2015 after the FA Cup final of Arsenal on Aston Villa, McCabe said: “What do we think of Tottenham?” To which the crowd replied: “S ** t!”
The full-back then shouted: “What do we think of S ** t?” Before the fans then answered: “Tottenham!”
The second mascot of Arsenal, a Labrador called Win, also appeared at the celebration.
After the trophy lift she was lifted to the crowd by Mead.
Said about the competition, head coach slangers said: “I am often very calm and there are many thoughts and feelings in me. When the whistle blew before the final, I knew we had two weeks of preparation.
“We were so prepared. We were ready, let's go and see where we are and go for the victory.
“We work with the players and the staff every day, there is an incredible work. When we get on the field and you see, it really makes it all. Thank you very much, you have been incredible.”
