Selena Gomez gave Coldplay fans an extra treat when she made a surprise appearance at the band’s concert on Sunday night.

The enduringly popular British rock band was performing at the Rose Bowl Stadium in Pasadena, near Los Angeles, when the 31-year-old actress and singer sauntered out on stage without warning.

Selena — who nearly had a run-in last month with her on–off nemesis Hailey Bieber — was on hand to back up frontman Chris Martin, 46, after he launched into a performance of the band’s 2021 hit Let Somebody Go, which had originally featured additional vocals from the Only Murders In The Building star.

He initially invited two young fans from the audience to join him at an electric piano as he launched into what looked like a solo version of the original vocal duet.

But as he started playing and singing, the stadium erupted in a roar of cheers as Selena strutted out mid-song, which also shocked the two young fans on stage.

In video that Selena posted of the performance to her Instagram Stories, as well as a clip shared by Coldplay on its Instagram account, she could be seen offering the fan on the outside of the piano a quick hug, and then she and the other fan could be seen high-fiving and looking visibly overwhelmed by the guest appearance.

Selena looked chic and stylish in a black long-sleeve dress with a maxi skirt.

She wore her long raven tresses parted down the middle and styled in voluminous waves that fanned out over her shoulders and back.

She also wore shimmering black boots, and a set of particularly thick silver hoop earrings framed her impeccably made-up face.

The rest of the band appeared to have gone backstage, leaving Chris Martin alone on a circular stage for the moment, and the lights had been turned down for the intimate moment, which made Selena’s all-black outfit and dark hair almost disappear in the dim light.

What started out as a solo performance before turning into a duet then morphed into a trio when another figure stepped out of the shadows.

As the lights began to illuminate more of the stage, the singer H.E.R. stepped out in an intriguing purple sweatsuit covered in glittering sequins.

She layered more sweet vocals on top of Selena and Chris, before taking the spotlight for a moving guitar solo.

Selena’s video of the all-star performance showed an utterly rapt audience, and the fans surrounding the stage whipped out their phones to preserve the moment for posterity.

‘Thank you @coldplay @hermusicofficial for an amazing night,’ Selena wrote on Instagram in a follow-up Insta Stories post.

She showed off her slinky black dress in a mirror selfie while raising one leg suggestively and showing off her fishnet stockings.

The song, which Selena is not a credited writer on, was begun around 2019, and finished in 2021.

It was initially considered for inclusion on 2019’s Everyday Life album, before being added to Coldplays 2021 LP Music Of The Spheres.

Chris also credited his daughter Apple Martin with supplying him with an intriguing chord that became an important part of the song, though it apparently wasn’t a large enough contribution to earn her a credit among the nine other credited songwriters.

Nearly two years ago, Selena first joined Coldplay for a live performance of Let Somebody Go on the October 18, 2021, edition of the now-defunct Late Late Show With James Corden.

But she wasn’t always on hand, so Coldplay also performed the song as a solo number, with Chris Martin performing a version on his own during a February 2022 appearance on The Ellen DeGeneres Show.

Although Let Somebody Go only charted in the 90s on the Billboard Hot 100 singles chart, it reached number 24 on Adult Top 40 chart and number nine on the Hot Rock & Alternative Songs chart, while it also did well in the UK and other countries.

Selena has had her own recent hit with the summer release of her latest song, Single Soon.

Her fans recently wondered if she had had a run-in with her ex Justin Bieber’s wife Hailey Bieber when the two were spotted at the same restaurant in Paris to coincide with Paris Fashion Week.

However, TMZ reported that the two had been dining on different floors, and they didn’t come into contact with each other before exiting.
