Marvin, who is dad to six-week-old Alaia-May, arrived at the Arqiva Commercial Radio Awards at Westminster Park Plaza before posing for pictures on the red carpet.
The 28-year-old, who is the voice of Capital FM on the weekend after landing a Saturday night show in addition to his Friday night slot, was suited and booted in a purple number by bespoke tailor, Marc Wallace.
Marvin, who teamed his suit with a pink tie and tan suede shoes, later tweeted: "Thank you to @MarcWallaceLtd for hooking me up tonight for the Arqiva Awards tonight.. Suit and Tie Vibes."
Marvin was all smiles as he posed for photographers before celebrating the very best radio talent. But despite rubbing shoulders with industry professionals, it seems like the boy band star couldn't wait to get back to his family.
Once he had arrived home from the awards ceremony, he told his Twitter followers: "Home sweet home to R&A Humes.. My lifelines x."
Marvin and his wife Rochelle, who welcomed their daughter on 20 May, haven't stopped gushing about their bundle of joy. Last month, Marvin declared: "It's just the most beautiful feeling. You're just filled with such emotion that you've never felt before."
