Lady Gaga has joined forces with global payment provider and bank Klarna on a new campaign ahead of Leap Year, 'giving the finger to outdated traditions', spreading the message 'that we are all free to propose to anyone at any time', despite tradition suggesting it's only acceptable for women to propose to their partner on February 29.

The Shallow hitmaker models Klarna's limited edition Knight Finger ring, designed by fashion activist and stylist B Åkerlund, and commented 'For my entire career, I've taken pride in using my voice to stand up for what I believe is right. So I am excited to work with my friend B. and Klarna to celebrate how far we've come as a culture, and call out the work we need to continue to do... So in an act of defiance of this outdated tradition, I decided to say yes to MYSELF!'.
