Madonna surprised fans at Coachella making a guest appearance during Sabrina Carpenter's Friday night headline set.
The Queen of Pop joined Carpenter on stage for a duet of Vogue, Like A Prayer and a song from Madonna's new album.
The performance followed days of speculation that Madonna would appear at the festival in the Colorado desert in California.
On Wednesday, Madonna officially confirmed the release of 'Confessions II' - a sequel to her 2005 'Confessions On A Dance Floor.'
After Carpenter finished a rendition of Juno, Madonna emerged while the intro of Vogue played out and dancers struck a pose.
With matching blonde hair and lace corsets, the pair sang the 1990 house hit, before strutting across the stage to perform 'I Feel So Free' from Madonna's new album.
Speaking to the crowd, Madonna said: Twenty years ago today, I performed at Coachella - I was in the dance tent and it was the first time I performed 'Confessions On A Dance Floor: Part I' in America and that was such a thrill for me.
She added, So you can imagine what a thrill it is for me to be back 20 years later... so it's a like a full circle moment you know - very meaningful for me, before discussing the astrology of the New Moon in Taurus with Carpenter.
The 5ft 4in star then pointed out it was the first time she has performed with someone shorter than her. Thank you for giving me that experience, Madonna joked.
The duo then joined forces for a duet of 'Like A Prayer.'
Madonna first appeared at Coachella in 2006, popping up at the Sahara Tent instead of the main stage to perform 'Confessions On A Dance Floor.' She later returned to the desert, making a guest appearance during Drake's 2015 set.
The collaboration came in Carpenter's second week headlining the festival, which draws more than 100,000 people daily at Indio's Empire Polo Club since 2002.
