Though, let's face it, he always looks good, right?!
It may only be September but gorgeous Calum proved it's not too early to start thinking about looking fab over the festive season, as he modelled a slick 'n' sharp suit from the Burton Christmas range.
Fancy getting your hands on Calum's suit for your other half, your brother or other family member? The jacket is £80 and the trousers are £40, both available from the Christmas collection, which hits Burton stores at the end of October.
Calum told Reveal at the bash: "I really like the collection – I'm wearing it tonight. I just added the braces myself. I like to add touches like that to make menswear styling more original.
"I go for interesting detail – like bright-coloured socks, or great designer shoes that combine classic fabrics in a way that's unusual," he continued. "The suits are a really good fit – like this slim-cut one I'm wearing."
Other key pieces include a Prince of Wales check three-piece suit for £180, a camel coat for £85, a khaki bomber jacket for £40 and a burgundy lambswool blazer for £85. The collection, which is described as "timeless and masculine with a contemporary twist", boasts 100% Shetland wool, Italian weave tailoring and a range of leather accessories.
Calum was joined at the glitzy event by a slew of famous faces, including recent Celebrity Big Brother housemate Fatman Scoop and designer Julien MacDonald.
