Capital’s 2023 Summertime Ball with Barclaycard kicked off earlier on Sunday with performances from a star-studded lineup including The Jonas Brothers, Calvin Harris, Tom Grennan and former One Direction star Niall Horan.
One mega star who wasn't listed on the bill but caused a huge stir with a cameo appearance was none other than pop superstar Kylie Minogue.
The Australian megastar, 55, stunned 80,000 fans at Wembley Stadium as she popped up from underneath the iconic stage to perform her brand new song 'Padam Padam' from her forthcoming album 'Tension'.
And with the screaming crowd in the palm of her hand, Australian singer Kylie then treated fans to a rendition of her 2001 hit 'Can’t Get You Out of My Head'.
Age-defying Kylie stunned as she took to the stage in a bright red dress which featured daring waist-high splits on either side.
While her performance went down as arguably the best moment of the entire day, Kylie's appearance at Capital's 2023 Summertime Ball with Barclaycard, just a couple of days ago, the Aussie singer wasn't sure if she would take to the stage.
Speaking of her performance on the night, Kylie said: "It was the best surprise. It was almost a surprise for me, it really was very last-minute. We just flew on in."
Kylie said that she had 'no idea' a week ago that she would be performing to 80,000 people at Wembley Stadium
"To be able to do ‘Can’t Get You Out Of My Head’ after, I had the best time. Thanks to everyone," she told the press.
Before taking to the stage at Wembley, Kylie teased her performance on Instagram for all of her fans to see as a video saw her crouched down underneath the stage before she popped up in front of 80,000 screaming fans.
"When you're about to PADAM PADAM at WEMBLEY STAAAAADIUUUM! What a treat to surprise you all at Summertime Ball," she captioned the footage.
Kylie revealed in May that her upcoming record Tension will be a 'blend of personal reflection, club abandon and melancholic high' when it will be released in September.
Her single from the album, namely, Padam Padam recently reached the top ten of Billboard's Hot Dance/Electronic Songs chart for the first time.
The catchy track soared up from the No. 12 spot to No. 10 on June 10, according to Billboard.
Kylie wasn't the only surprise act at the Capital Summertime Ball this year however, as UK Eurovision singer Mae Muller also took to the stage - much to the delight of the crowds.
Fresh from her Eurovision performance in Liverpool last month, Mae, 25, said she feels like she can take on any challenge after performing at the 2023 Eurovision Song Contest.
Mae exclusively told The Mirror that her journey from being announced as the UK entry to taking to the stage in Liverpool on May 13 had it's 'ups and downs' but was an experience she will never forget.
Global stars likes Sir Ringo Starr and Lana Del Rey backed Mae ahead of the final at Liverpool Arena, with the entire country becoming obsessed with the Gen Z icon's catchy entry tune, I Wrote A Song - with the track boasting over eight million streams on Spotify.
But the nation was left gutted when Mae found herself finishing in 25th place with a total of just 24 points - a placing many Eurovision fans felt was harsh and undeserved for such a talented act.
Reflecting on her Eurovision stint at Capital presents Summertime Ball with Barclaycard today, Mae gushed over the support she received from the public and revealed how are direct messages on social media look since becoming a household name.
"Probably the biggest thing I learned about myself [when representing the UK at Eurovision] is that I'm a strong ass woman!" Mae declared when chatting exclusively to the Mirror ahead of performing at Wembley Stadium.
"Honesty, I'm going to say that right now - It was such an amazing experience and I gave so much, the support was incredible and I feel so thankful for everybody, but it's not an easy feat.
"There were a lot of ups and a lot of downs and I think I came out of that. Now I think 'If I can do that, I can literally do anything.
"I'm feeling stronger and like I can take on whatever."
