Despite performing their hit song, Elton John was on the Glastonbury Pyramid Stage without fellow musician Dua Lipa on Sunday night.

The 27-year-old pop star missed her chance to duet "Cold Heart" with him, so Elton requested the audience to sing Dua's part of the song.

Fans labeled Elton's spectacular closing of his last UK tour as the "best Glastonbury headliner ever."

Although it should have been a triumphant moment to share with Dua, the duo had to celebrate apart due to their conflicting schedules.

On the day Elton performed his final show, Dua posted photos of a family meal instead.

One person believed Elton John's headlining performance at Glastonbury was more crucial than her current whereabouts.

An individual on social media queried: "What did Dua Lip unfortunately decide to do other than take part in Elton John's last UK performance?"

Another person remarked: "It is regrettable for Elton John that Dua Lipa chose to opt out of appearing at #Glastonbury, which was the first show she skipped in three years."

"I'm dying to know what Dua Lipa chose to do rather than perform with Elton John on his final UK performance," a third said.

Fans immediately discovered what the "Levitating" hitmaker was up to when she could have been performing with the award-winning singer-songwriter.

Dua shared pictures to her Instagram from a family meal, rumored to have taken place in New York.
