And she was joined by royalty!
Take That - Greatest Day
'Greatest Day' debuted at number one in the UK and became the band's 11th number-one single.
The boys premiered the track at the 2009 BRIT awards and it's now gone on to sell over 400,000 copies.
The music video was filmed on-location in downtown Los Angeles, on-top of a 60-storey building.
It was directed by Meiert Avis, who has previously shot videos for the likes of U2, Bruce Springsteen and Bob Dylan.
She took the mirror selfie before the reverse camera was even a thing! Say what?!
