The single is in support of the Elton John AIDS Foundation, which was founded in 1992 and is one of the leading independent AIDS organisations in the world.
Elton and Olly had been majorly teasing their joint performance on social media in the lead-up the the ceremony, with their Instagram accounts and the Brits page all sharing words that spell out 'It's A Sin.'
Reaction: Some viewers even gushed that the colourful performance was 'the best ever' in the music event's history
New music alert! The tune has now been released as a single in support of the Elton John AIDS Foundation
Sir Elton got the rumour mill going on Monday night by posting the word 'It's' on a brightly coloured background, before Years & Years dropped the word 'A' in an identical font.
Fuelling the speculation further, the official Brit Awards page then posted the word 'Sin', getting fans excited for what will no doubt be an epic performance.
It was reported that they'd be teaming up to perform a cover of the Pet Shop Boys' hit It's A Sin, which of course shares its name with the critically acclaimed series which starred Olly.
Elton was a huge fan of It's A Sin when it aired on TV earlier this year and even shared his appreciation on social media.

How are the BRIT Awards going ahead during the Covid pandemic?
The 2021 BRIT Awards mark the first live music event in the UK since the start of the Covid-19 pandemic.
The indoor ceremony and live show will form part of the Government's scientific Events Research Programme.
Enhanced testing approaches will examine how events can take place without the need for social distancing after all restrictions are lifted on June 21.
4,000 tickets were made available for the live ceremony, just one fifth of the venue's 20,000 capacity, with 2,500 of those being given to key workers.
The BRITs will play an important role in paving the way for the return of live music at scale as the UK emerges from the past year's restrictions.
Audience members will not be socially distanced or required to wear face coverings once seated inside the arena, though they will be required in communal areas such as the toilet or main concourse.
All attendees will be allowed to purchase alcohol and concessions once inside the O2 Arena.
Attendees will also be required to follow existing Government guidance when travelling to the venue and adhere to rules set out by the event organisers.
Among the rules, attendees must have proof of a negative lateral flow test result to enter the venue, and said test must be taken at an asymptomatic testing site within 36 hours of the ceremony.
Upon arrival at the venue, all attendess will be asked to take a PCR test, and will then take another test five days after the ceremony
It's hoped this will gather further evidence on the safety of indoor settings, reduced social distancing and the removal of non-pharmaceutical interventions like face coverings.
He wrote: 'It’s A Sin is an incredibly moving account of the arrival of AIDS in the UK in the 1980’s.
'Watching it, so many sad and devastating memories came flooding back. Many people were callous, ignorant and cruel. Thank God we have come so far since then.
'Hats off to @russelltdavies63 on creating this moving testament to a pivotal and important moment in LGBTQ history. The cast are sublime. Congratulations all round. A triumph of creativity and humanity.'
From multi-BAFTA Award-winning writer Russell T Davies, It's A Sin follows the story of the 1980s, the story of AIDS, and charts the joy and heartbreak of a group of friends across a decade in which everything changed.
Putting on a show: Several backup dancers joined the star on stage
All for a good cause: The single is in support of the Elton John AIDS Foundation, which was founded in 1992 and is one of the leading independent AIDS organisations in the world
With the host: Jack Whitehall jumped in for a snap with the musical duo
Fan: Elton became a huge fan of Olly's performance as Ritchie Tozer in Channel 4 drama It's A Sin (pictured with the show's cast)
Olly starred alongside a cast of rising stars and celebrated favourites including Keeley Hawes, Stephen Fry and Neil Patrick Harris and It's a Sin has been universally praised by fans.
Davies, the writer and producer behind Queer As Folk, the 2005 revival of Doctor Who and Cucumber, loosely based It's A Sin on his own experiences in the eighties.
He also spent hours in conversation with his childhood friend Jill Nalder, an actor, ally and activist who lived in London during the decade and is played by Lydia West in the drama.
Big night out: Elton was joined at the BRIT Awards by his husband David Furnish
Larking around? Jack and Elton seemed to be in good spirits as they chatted on the stage
Such a fan was Elton that he even invited Olly and the entire cast to dinner while on a phone call with the singer on his Apple Music 1 radio show in February.
He said: 'I told you when I called you, when this COVID thing has calmed down I'm going to have all of you guys down for a dinner and we're going to have the best time!'
He also praised the show as the 'best thing' he's ever watched, saying: 'I have to say, being a gay man and having lived through that time, this is probably one of the best things I've seen on television, ever!
'For those of you who haven't seen it, you must see it, it will have a lasting impact.'
