Nick, who hosts the BBC Three comedy panel show, dons Dot's famous wardrobe staples including her trench coat, scarf and handbag. And of course, no Dot transformation is complete without a lit up cigarette!
In a mock-up set of the famous Queen Vic pub in Albert Square, which has been re-named The Queen's Nick, the sketch sees Dot on her lonesome in the pub until a local arrives.
Nick takes part in the sketch alongside Sweat The Small Stuff's team captain Melvin O'Doom and celebrity guest Lacey Turner. And guess who Melvin dresses as? None other than Phil Mitchell!
Yes, Kiss FM presenter Melvin does his best hard-man impression as he talks to Dot in the pub.
And in a new photo from the sketch, Lacey, who plays Stacey Branning in EastEnders, can be seen pulling a pint with Dot by her side.
We wonder what June Brown - who plays the iconic character of Dot - thinks of Nick's impression?!
This isn't the first time that Nick has made his love for EastEnders known. Last year, the Radio 1 DJ made a cameo appearance in the soap as a cleaner! Nick landed the role as part of his 'soapbombing' spree, which saw him gatecrash the most popular soaps, including EastEnders, Coronation Street, Emmerdale, Hollyoaks and Home and Away.
Sweat The Small Stuff features special guests during each episode, with Nick, Melvin and Rochelle Humes discussing their daily obsessions, pet hates and personal dilemmas.
Sweat The Small Stuff airs tonight (Wednesday 5 November) at 10pm on BBC Three.
