The pair, who announced they were an item last month, looked loved-up as they posed together alongside their mothers at the Manchester ceremony.
However, things took a cheeky turn when it was announced that Rob, 25, had won the Best Newcomer statuette.
The Daniel Osbourne actor shocked and amused the star-studded guests with his acceptance speech, that of course included a mention for his boyfriend.
The soap star started: “I don't know what to say… I want to thank Kate Oates, Kieran Roberts, Tony Hammond and Hannah Sowden for pitching the return of this character.
