Sombr, Olivia Rodrigo and all the stars rumoured for Capital’s Jingle Bell Ball 2026

Sombr, Olivia Rodrigo, Mariah Carey and John Legend are among the huge names rumoured to be in the running for Capital’s Jingle Bell Ball 2026, as fans look ahead to one of the biggest music events of the festive season.

The annual concert is expected to return to London’s O2 Arena on Saturday, December 5, and Sunday, December 6, with a star-studded line-up tipped to bring some of the biggest names in pop, dance and R&B to the capital.

Sombr has emerged as one of the most exciting names in music, making him a major contender for this year’s Jingle Bell Ball line-up. The singer-songwriter, whose real name is Shane Boose, broke through with his viral hit back to friends, winning over fans with his emotionally charged lyrics and indie-pop sound. With his growing popularity and a string of successful releases, a performance at London’s O2 Arena would be another major milestone in his rise. However, Sombr’s appearance at the December event remains a rumour for now, with fans awaiting official confirmation from Capital.

While Capital has yet to confirm this year’s performers, speculation is already building around which artists could take to the stage for the two-night spectacular.

And if the current rumours are anything to go by, music fans could be in for a seriously exciting weekend.

Is Olivia Rodrigo performing at Capital’s Jingle Bell Ball?

Olivia Rodrigo is among the biggest names being tipped for this year’s event, alongside rising star Sombr.

Both artists have enjoyed major success with their music, making them exciting possibilities for the festive concert. Olivia has become one of pop’s biggest stars thanks to hits including drivers license, good 4 u and vampire, while Sombr has built a growing following with his alternative pop sound.

However, neither artist has been confirmed for the London event, and fans will have to wait for Capital’s official announcement before making any plans.

John Legend and Mariah Carey also rumoured

According to reports from The Sun, John Legend is in advanced talks to headline the event, while Mariah Carey is reportedly being considered for a special guest appearance.

Legend, known for his soulful vocals and romantic hits, would bring a different musical flavour to the line-up, while Carey would be a particularly fitting addition to a concert taking place just weeks before Christmas.

The pop icon’s festive classic All I Want for Christmas Is You has become a seasonal staple, making her a potentially huge draw for audiences attending the December event.

Becky Hill and Jamie Miller have also been mentioned in reports surrounding the possible line-up.

It is important to stress that these names remain unconfirmed for Capital’s Jingle Bell Ball 2026.

Which other stars could perform at Jingle Bell Ball 2026?

The rumoured line-up features a mixture of established chart stars, emerging artists and dance music favourites.

Other names being tipped include:

• Sombr

• Stella Lefty
• ADÉLA
• Becky Hill
• Alex Warren
• KATSEYE
• Jamie Miller
• HUGEL
• Ismael Angel
• Ultra Naté
• Troye Sivan
• Ashe

From KATSEYE’s global pop appeal to Becky Hill’s dance anthems, the potential line-up would offer something for fans of several different genres.

Alex Warren has also become a major name in pop, while Troye Sivan and Ashe would bring their distinctive sounds to the event if they were to join the bill.

Dance music fans could also have plenty to look forward to, with HUGEL, Ismael Angel and Ultra Naté among the names circulating in connection with the show.

As always, the rumoured line-up should be treated with caution until Capital officially confirms its performers.
