The Backstreet Boys and Westlife team up for incredible live-stream duet on two of their iconic tracks

Two of the world's biggest boybands from the '90s teamed up for a special virtual concert over the weekend - and it was pure pop heaven.

With a global audience of over 44 million WeChat users tuning in, the Backstreet Boys invited Westlife to join them on the live stream to perform two of their iconic songs.

First, the groups belted out Westlife's number one single 'My Love,' before they took on the Backstreet Boys' ballad 'I Want It That Way.'

Following the performance, Westlife took to social media to share a clip of the performance, writing: "It was an honour to be invited to sing with @backstreetboys on one of their biggest hits and also a very special moment for us to them to sing one of our biggest songs.

"An incredible moment for everyone involved and knowing that 44m people tuned in is just mind blowing!"

Talk about pure joy for all '90s kids.
