Photographs show Rita Ora's party after she is said to have voluntarily paid £10,000 for breaking coronavirus lockdown rules.
The singer apologised for the "inexcusable" event after she invited some of the great and the good of the showbiz world to her 30th birthday party.
It's said the songstress paid a voluntary £10,000 fine after she spoke to police about the bash.
MET Police told Mirror Online: "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 but found no indication of any offence being committed at the time.
"Officers continue to assess the allegations and are liaising with the local authority regarding a potential breach of regulations at the premises.
Later, the hostess was seen saying goodbye to her pals before they all went their separate ways.
Rita made a mesmerising exit in a silver skirt and furry coat at Casa Cruz restaurant in Notting Hill, West London.
Dressed immaculately, the singer had styled her golden locks into springy corkscrew curls especially for the occasion.
Temperatures were cooling in the capital so naturally Rita added layers to her party outfit including a coat and gloves.
At times, Rita was seen wearing her coronavirus face mask.
Photographs captured police in action at the restaurant where the party had taken place.
Officers swooped to the scene in London where they were seen looking into windows.
Parties and mixing remains banned under the latest coronavirus guidelines until December 2.
Restaurants had to close their doors for the second time this year but they were allowed to sell takeaways.
The UK was plunged into the second national lockdown in a bid to tackle the spike in Covid-19 cases.
Rita shared a grovelling apology to fans after she come under fire on social media for hosting the star-studded event.
In a statement Rita said: "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."
A Met Police spokesperson told The Sun: "Police were called at 9.10pm on Saturday to reports of a potential breach of Covid regulations in W11."
Social media was awash with criticism as fans slammed Rita and her guests as "selfish" for breaking the Covid-19 rules.
"Rita Ora that is so not cool of you hosting a party in lockdown - very selfish behaviour - do you think u above the law - shameful really," fumed one.
Others added: "30-years-old and behaving like a spoilt child! You don’t think the COVID lockdown rules apply to you? You’re happy to risk spreading the disease for your own selfish vanity? Shame on you!!!"
"A colleague’s mum just died and then I see your selfish , nonsensical and egocentric behaviour. Maybe you should take a trip to your local ICU, care home etc. What the hell were you thinking!"
Mirror Online has approached Rita's representative and the MET police for comment.
