The Sugababes surprised commuters at King's Cross in London as they treated them to a surprise performance on Thursday.
The girl group shocked passers by as they appeared out of a large Sky Broadband platform set up in the train station.
The group performed their hit song Push the Button after members of the public were seen pressing a giant button on a billboard.
The trio, made up of Mutya Buena, Keisha Buchanan and Siobhan Donaghy looked incredible for their surprise show.
Mutya, 39, wore a black crop top that highlighted her toned midriff and paired it with a matching bomber jacket and pink trousers.

Keisha, 40, opted for a purple jacket and matching trousers along with a black bralet while Siobhan, 40, sported a purple long-sleeved top with black leather trousers.
The performance was part of a campaign for Sky Broadband, which saw the band become the Suga Broadband Babes to highlight how easy it is to change broadband providers.
It comes after the original trio took a brutal swipe at their former band members.
Keisha, Mutya and Siobhan formed the iconic girl band in 1998.
However, the lineup saw several shake-ups after Siobhan left in 2001, replaced by Heidi Range - with Mutya and Keisha eventually being replaced in the mid-2000s by Amelle Berrabah and Jade Ewen, respectively.
Now, appearing on Will Manning's Capital Breakfast show on Thursday, the OG members reflected on the group's formation over the years, stating that they will always be the best and ‘the essence’ of the group.
'You three are the OG Sugababes but out of all the versions, which one do you think was the best?' asked Will.
Mutya quipped: 'The first one!'

'I think the thing is, we started it when we were young teenagers,' Siobhan said, while Mutya added: 'It’s our baby.'
Siobhan continued: 'And I think there will always be something about the Sugababes that is this for us, it is where it started, and it is the essence of what it is.'
'It makes sense,' Will replied.
It comes after the girl band announced that they are set to hit the road for their 'biggest ever UK and European tour' in spring 2025, with shows lined up in cities such as London, Birmingham, and Cardiff.
The original members reunited in 2019 and have since sold out The O2, shut down Glastonbury stages twice due to demand and performed to record breaking crowds at European gigs.
