The reality TV star was spotted out and about in the capital on Wednesday (18 December) picking up gifts for his friends and family and showing off his tattooed arms in a short-sleeved, black and white T-shirt. Wasn't he freezing?!
Dan also looked effortlessly cool in a pair of drop-crotch black trousers and some Nike Air Jordan trainers and even decided to jump around in the rain to prove that he is immune to the plummeting temperatures.
One of his friends uploaded a picture with a caption that read: "Cant take @DannyO anywhere, this is in the pouring rain bear in mind! Haha!"
We have to admit, we're not all that surprised to catch the hunky Essex star ditching an extra layer and flaunting his guns, since he is often seen posing for photos with minimal clothes on!
Earlier this month, Dan gave his fans a real treat by baring all and becoming Reveal's Stripping Santa.
And we couldn't take our eyes off him!
The TOWIE newbie and tattoo artist is also a fan of gym selfies and frequently posts snaps of himself after an intense workout - topless of course.
However, despite being quite a hit with the ladies (past romances have included co-star Lucy Mecklenburgh and EastEnders actress Jacqueline Jossa) Dan isn't looking for love this Christmas.
Instead, he is focusing on fatherhood and getting ready for the arrival of his first son, who he is having with his ex-girlfriend.
He told Reveal: "I'm single at the moment, I'm focusing on my role as a dad. Let's just say I'll be avoiding the mistletoe this Christmas!"
