Two mega, superstar collaborations happened this weekend.
Each one had one a huge American female star coupled with a multi-million selling British frontman - but whose was best?
Number one. She's had everyone from her Cara Delevingne-fronted girl squad to Steven Tyler on stage during her '1989' tour.
But Taylor Swift saved Mick Jagger as a VIP guest for one of her hometown gigs.
Teaming up for the Rolling Stones 'Satisfaction' on the second concert at Nashville's Bridgestone Arena, the pair strutted and stalked up and down the stage, with the veteran rocker giving it his all on his quick trainer, tippy-toe feet.
From the looks of it, he was even more excited to be there than Swift...

The second saw Ed Sheeran join Queen B onstage at the 2015 Global Citizen Festival for a rendition of Drunk in Love, which we all know the naughty lyrics to.
It's tough to pick one over the other. While Mick's moves are infectious and puts a smile on the face, Ed brings on a ruddy cheek asking Beyonce to ride on his surf board...
He does well keeping composed to be honest, probably because Mr Beyonce is watching from the wings...
