So, what is #FirstSNOG?
It's a social media campaign by LGBT rights charity Stonewall for their 25th anniversary.
The organisation has created an app in collaboration with the frozen yogurt company SNOG.
They have explained, "SNOG Frozen Yogurt believe people all around the world should be free to snog whoever they want, whenever they want."
SNOG has commissioned designer Carri Munden of fashion label Cassette Playa to develop an exclusive app people can download in order to become a part of an Insta-gallery.
Stars including Russell Brand, Harry Styles, Alan Carr, Sam Smith, Rita Ora, Laura Whitmore, Florence Welch, Jodie Harsh, Boy George, Noel Fielding, Katy B, Nick Grimshaw, Calvin Klein and Karen Elson have all got involved.
A donation of £3 can be made to Stonewall by texting 'SNOG' to 70300.
