Selena Gomez surprised fans during a Rare Beauty promotional event in London on Tuesday by allowing them to stream her playing her not-yet-released single.

The upcoming song – most likely тιтled Call Me When You Break Up – is a duet between the 32-year-old ‘Texican’ pop star and Gracie Abrams, and the bouncy track was produced by her fiancé Benny Blanco.

‘Oh I get so nervous!’ Selena cringed while introducing the song as her fans stood nearby.

‘Call me when you break up / I wanna be the first one on your mind when you wake up,’ Gomez sang along with the lyrics.

‘I miss the way we’d stay up / We talk about forever when I’m taking off my make-up.’

The two-time Grammy nominee looked slim and leggy in a $950 red Roland Mouret ‘Long Sleeve Tailoring Wool’ mini-dress and matching $975 Jimmy Choo ‘Ixie 80’ pumps selected by stylist Erin Walsh.

Selena – who has lupus – previously confessed to LADBible as recent as November 11 that she ‘doesn’t even go to the gym’ despite being the subject of rampant Ozempic rumors.

Hairstylist Renato Campora coiffed Gomez’s sleek brunette bob and make-up artist Hung Vanngo fully contoured her glowing complexion.

‘I’m so excited for you guys to share it, if you want, do whatever you want. I’m just so thrilled,’ the certified billionaire gushed to her fans.

‘To get the obvious statement out of the way, this song is actually about my best friend that I have in my life, so it’s not about anything if you think it is. But I’m so excited for you guys to hear this album. It’s been so much fun creating it with Benny and we’re just going to keep, hopefully, releasing some fun stuff. I hope you all like it!’

It marked the second single off Selena and Blanco’s collaborative album I Said I Love You First – dropping on March 21 – after they released Scared of Loving You last Thursday.

‘Sounds like something she would release in her early career. I love it!’ TikTok user @saturn.r3turns wrote.
