Today (21 April), the reality star turns 28 years old and to mark getting another year older, Kirk clearly wanted to have some fun on social media. Some naked fan, that is.
He decided to ditch his kecks and pose completely in the nude, before sharing the short clip on Instagram - just in case his fans hadn't yet had their fill.
We don't know where to look!
Kirk was in high spirits as he showed of his bare bum on camera. The cheeky chappy told his followers: "It's my birthday, so it's only fair that I'm in my birthday suit."
"That's me and that's my arse," he pointed out, before bursting out into laughter. Alongside his photo, Kirk added the caption: "I'm now 28 but still act like I'm 10 looool."
Oh, Kirk! Happy birthday.
This last year has been a pretty big one for the Essex boy, as Kirk became a dad for the first time.
He welcomed his daughter Violett into the world on 9 February and gushed at the time: "The time has arrived!!! I'm finally a dad! My little princess Violett was born yesterday and she's so beautiful!!!"
He added: "I'm finally a dad!!!! Words can't describe how I feel right now!!!"
Kirk shares Violett with Holli Willis, who he had proposed to back in September 2015. They had enjoyed a romance seven years ago, before reuniting and rekindling their relationship after meeting again in a restaurant.
It is rumoured that Kirk and Holli have now split, but neither have publicly spoken about their relationship status. Instead, Kirk shared several pictures of Violett following her birth and told fans he loves her "more and more each day."
