The reality TV star had just wrapped up an intense workout and was clearly proud of his results, since he swiftly took a snap of his bare chest to show his Twitter followers.
Dan posted the sexy snap on Twitter on Thursday evening (15 August) and wrote: "Just finished today's gym session.. This training is killing me now!"
The bathroom 'selfie' sees the 22-year-old tensing his swoon-worthy abs while wearing a pair of black shorts and giving us a glimpse of his intricate body art.
It's no secret that Dan is a fan of tattoos (he is a tattoo artist after all!) and he has built up quite a collection, which cover his arms and the side of his chest.
The TOWIE newbie caused quite a stir in the latest series of the show, after revealing that he was expecting a baby with his ex-girlfriend - something that he discovered while enjoying a fling with co-star Lucy Mecklenburgh.
But since calling things off with Lucy, Dan hasn't been able to contain his excitement at the thought of becoming a dad and even announced last week that he will be having a little boy.
We can imagine he'll be taking his son down to the gym as soon as he's old enough!
