Why has she gone publicly just now you ask? Well, Delevingne revealed on the TrevorLIVE Gala red carpet in New York City that it is particularly special to her as is the couple's one-year anniversary and also the Stonewall Riots 50th anniversary.
And if that's not enough to turn you into mush, the Suicide Squad star gave her actress girlfriend a shout-out during her acceptance speech after being given a 'Hero Award' at the star-studded event.
She said: "I also have another very special woman in this room to thank and you know who you are. She's one of the people who helped me love myself when I needed it most and I really needed it. She showed me what real love is and how to accept it, which is a lot harder than I thought."
Happy Pride, everyone!
