WATCH: This weekend, the surprise guest phenomenon went next level. And we loved it.

It’s Taylor vs Tyler.

It’s not exactly unknown information that Taylor Swift has a (teeny, tiny) habit of flaunting her many, many A-list connections up on stage during her 1989 tour performances. Her audiences have already been delighted by impromptu Victoria’s Secret catwalks, duets with the likes Selena Gomez and our personal favourite, a performance with Lisa Kudrow to sing ‘Smelly Cat’.

But if you thought TayTay’s friends were only models and stunning actresses you would be wrong.

This weekend Taylor was joined by an unlikely guest, Aerosmith frontman, Steve Tyler.

The pair sang his band’s 1998 hit, “I Don’t Want To Miss A Thing” in front of thousands of screaming fans. (Post continues after video.)

Taylor wasn’t the only pop QUEEN to perform an unusual duet this weekend, either.

Beyoncé teamed up with Everyones-Favourite-Red-Haired-Dude-With-A-Lion-Tattoo, Ed Sheeran.

Queen Bey was performing at New York’s Global Citizen fest in Central Park when she welcomed Ed and his trusty guitar on stage for an epic performance of “Drunk In Love”.

While the vision of a glittery-leotard-wearing-Beyoncé standing next to a checked-flanny-clad Ed was slightly odd, we think their acoustic rendition definitely worked.

What did you think of the Taylor/Steve Tyler and Beyoncé/Ed Sheeran duets?
