After a staggering 14 nominations and loses, the Scottish DJ took home not one but two go the coverted gongs.
As well as being named Best Producer, Calvin won Best British Single for his Dua Lipa collab One Kiss.
Posing on the red carpet with his awards, the We Found Love hit-maker looked happier than ever as he clutched his his BRITs.
Dressed in a shiny green suit the 35-year-old lapped up the attention as cameras flashed around him.
Taking to Instagram, Calvin shared three backstage snaps with his fans simply captioning them “Brits 2019”.
While many fans commented on the snap with messages of support fellow DJ Benny Blanco.
The Eastside hit-maker crudely replied: “I can see your [aubergine emoji].”
Benny’s comment was quickly picked up by shocked supporters.
“I can see your [aubergine emoji]”
One fan added: “I can’t unsee this now.”
“How many people just zoomed in to see if they can see it as well,” a second continued.
Meanwhile, a third added: “It’s saying hello!”
Keen to celebrate his double win, Calvin kept the party going into the small hours after rocking up at the Sony Music After Party.
Held at aqua shard – 31 floors up the ionic building – the music giant went all out to host their biggest and best bash yet.
Joined by girlfriend Aarika Wolf, Calvin was seen checking out the panoramic views of the city as he played on roulette tables dotted around the venue.
