Rita Ora's 30th birthday venue Casa Cruz reportedly could lose its licence over the "inexcusable party".
Casa Cruz has a huge celebrity clientele with the likes of Victoria Beckham and Nick Jonas often eating at the A-list restaurant.
But Met Police launched a bid to revoke the licence of Casa Cruz, in Notting Hill following the singer's extravaganza on Saturday November 28, according to The Daily Star.
The Notting Hill celeb hotspot would be unable to serve guests alcohol or play music to them if its licence is revoked.
A Met spokesperson told The Mirror: "A total of four people have been reported for consideration for a fixed penalty notice under ‘The Health Protection ( Coronavirus ) Regulations 2020’ for contravening requirements not to participate in an indoor gathering of two or more people.
"Officers continue to liaise with the local authority regarding a potential breach of regulations at the premises."
They added: "Police were called at 21:10hrs on Saturday, 28 November to reports of a potential breach of Covid regulations at a commercial premises in Clarendon Road, W11.
"Officers attended and carried out enquiries at the scene and following further enquiries by officers from Central West BCU."
Royal Borough of Kensington and Chelsea confirmed a virtual hearing will take place later in January.
A rep for the council told the newspaper: "The location, it is under review and will be discussed at a virtual hearing on Thursday 28 Jan."
The Mirror has requested a comment from Casa Cruz representatives.
Rita shared a grovelling apology with her fans when the news got out she threw an illegal birthday party where she mingled with friends and family.
The Lonely Together hitmaker said she was "deeply sorry" for the "inexcusable" party which she insisted was a "spur of the moment".
In a statement on her Instagram story, Ora wrote: "Hello all, I attended a small gathering with some friends to celebrate my 30th birthday.
"It was a spur of the moment decision made with the misguided view that we were coming out of lockdown and this would be OK…
"I'm deeply sorry for breaking the rules and in turn understand that this puts people at risk.
"This was a serious and inexcusable error of judgement. Given the restrictions, I realise how irresponsible these actions were and I take full responsibility.
"I feel particularly embarrassed knowing first-hand how hard people have worked to combat this terrible illness and being fully aware of the sacrifices that people and businesses have made to help keep us all safe.
"Even though this won't make it right, I want to sincerely apologise."
