Inside Taylor Swift's swanky thank you party at plush private members' club Annabel's in Mayfair: Singer treats her 200-strong crew to a free bar and parties until 3am at secret event ahead of her final leg of Eras Tour in London

Taylor Swift hosted a lavish thank you party for her 200-strong tour team at private members' club Annabel's in Mayfair, London on Tuesday night.

The hitmaker, 34, let her hair down with her crew and partied until 3am ahead of her final leg of the Eras Tour at Wembley Stadium.

She made sure the plush venue was kitted out with a free bar and organised six 52-seater coachers to transport people back to hotels around the city.

In pictures obtained by The Sun, Taylor channeled her inner Cher in a Clueless-inspired outfit for the night.

She stunned in a Vivienne Westwood checkered co-ord, teamed with a chic ruffled white shirt and lime green platform heels.

A source told the publication: 'Taylor is one of the most generous pop stars out there and she threw this party to thank her team for their hard work.

'She hired out Annabel’s for the night and put on a free bar so her team could let their hair down.

'They will be back hard at work tomorrow for the first night at Wembley. It was packed in Annabel’s as there were 200 of them there, but it was a great night. Everyone was so appreciative of Taylor’s efforts.'

Taylor returned back to London a day before her final leg of the London tour kicks off on Wednesday night. 

The singer - who already had three shows in June - will be wrapping up this leg of her tour with five more gigs.

Her upcoming five Wembley concerts could see private counter-terrorism security forces deployed to keep thousands of fans safe, according to reports.

Sources claimed the popstar's shows will be relying on the extra security in response to the Vienna terror plot which caused her to cancel all three shows in the city last week.

The singer was due to perform in front of an estimated 170,000 fans on August 8, 9, and 10 at Ernst Happel Stadium in the Austrian capital, but was forced to cancel after the horrific attack was exposed.

Reports have emerged that Swift will be using private counterterrorism security forces to protect her fans due to the ongoing London riots placing a major strain on local police

It has since been confirmed that radicalized teens aged 17 and 19 – including an ISIS fanatic – had 'planned carnage with bomb, knives and vehicle attack on young fans.'

Now reports have emerged that Taylor will be using private counterterrorism security forces to protect her fans due to the ongoing London riots placing a major strain on local police.

The decision comes after music performances are facing more attention following the bomb attack at Ariana Grande's concert at Manchester Arena in 2017 which killed 22 people and injured 139 - most of them children and teenagers.

Sources told US-based showbiz site TMZ that despite Wembley having high-level security measures in place and being one of the safest in Europe from a counterterrorism perspective, there are still concerns.

Previous performances of the star's Eras tour have seen throngs of her rabidly loyal fans, known as Swifties, gather outside venues and swarm shops - even if they don't have tickets.

Concert organisers in Austria said they had expected up to 65,000 fans inside the stadium at each concert and as many as 30,000 onlookers outside, where authorities said the suspects planned to strike. 

The number of fans outside has caused a headache for the security planners of the Wembley gigs, which are set to take place from August 15 to 20. They will be the last of Swift's international tour leg before she returns to North America.
