The former TOWIE star was spotted sipping on a fruit treat from Starbucks as he left Capital FM radio studios in London's Leicester Square.
Mark was wearing a long-sleeved black shirt and blue jeans, which although smart, wasn't ideal for the muggy weather!
Walking alongside Mark was his Take Me Out: The Gossip co-host Zoe Hardman, who had also visited the studios for a chat with Heart radio.
Zoe was supping on an iced mocha while wearing a pretty pastel pair of shorts, a cream top and a tailored jacket.
The TV presenter completed her look with beige wedge sandals and a pair of sunglasses. Equally as stylish, but slightly more suitable for the weather!
