Adele has been keeping a low-profile while she beavers away on her highly-anticipated fourth album, but she broke cover on Sunday night to let her hair down.

The Someone Like You singer was a guest at her friend’s Jay-Z and Beyonce’s Oscars after party at Chateau Marmont in LA.

Also at the star-studded bash was Polish TV presenter Kinga Ruisin who chatted with the 31-year-old singer before getting this snap, but admits she didn’t recognise her at first.

Captioning the photo, she wrote (in Polish): “At yesterday’s private party by Beyoncé and Jay-Z, I talked to Adele about … shoes (Adele in the photo after dropping probably 30kg!) …

“I know that sounds surreal. But listen from the beginning … It started with a conversation with Adele about my high heels. Honestly, I didn’t recognise her because she is so thin now!

She continued: “We talked and laughed until she said her name … The conversation with Adele was the ticket to a nice conversation with Rihanna. And then there was total madness!”

Also at the party were Leonardo DiCaprio, Bradley Cooper, the Kardashians, Kanye West and Travis Scott.

Adele has been following a new fitness and healthy eating plan following her divorce from husband Simon Konecki, which was finalised last September.

New music is expected to arrive at some point this year, almost five years since the release of her Adele’s last album, 25.

Following her split from her husband, Adele joked to her fans: “Bunch of fucking savages, [the new album] will be a drum n bass record to spite you.”
