Undateables star Fats Timbo leaves fans in hysterics as she dresses up as 'Gangster Grinch' for Halloween and twerks on the street in Oxford Circus

Undateables star Fats Timbo left fans in hysterics on Thursday as she opted for an unconventional Halloween costume. 

While many associate October 31 with all things spooky, Paralympics host Fats opted for a different festive theme as she dressed up as a gangster version of The Grinch, from the eponymous Christmas film. 

Taking to Instagram, the 27-year-old comedian, who was born with dwarfism, delighted fans as she shared a video in full costume dancing and twerking on Oxford Street. 

Fats - who prefers using the term little people - shocked onlookers as she strutted past in a furry green costume and Santa outfit. 

She captioned the video: 'Listen, Halloween’s where it’s at, yeah? Man’s just asking people the real questions: are you about the spooky life, or are you one of those Christmas lot?'

Fats added the hashtags: '#GangsterGrinchOnRoad #HalloweenHustle #NahToChristmas #LondonGal #grinchtings'. 

Fans were quick to comment, penning: 'Love this sooo much as someone who loves the grinch this is extra epic'; 'Love it'; 'Grinch with the moves'; 'You MUST be stopped!'; 'STOP THIS IS EVERYTHING! Made my day for real'; 'Bad gyal Grinch'.

Fats was no doubt hoping to replicate her success of last year's costume when she went viral for her video scaring local shoppers while dressed up as Chucky. 

Speaking exclusively to MailOnline, the Don't Look Down star revealed that she chose the serial killing doll for her costume because vile trolls had previously compared the two. 

She explained: 'People troll me saying I look like Chucky so I thought the best way to own it is by dressing like Chucky!  

'It has helped with my mental health so much blocking trolls straight away and certain key words.

'If you get a viral video, it's best not to look at the comments because as well as good comments you're gonna see a lot of bad comments and it's human to focus on those.' 

Social media star Fats found fame after appearing on Channel 4's The Undateables in 2018 and also took part in Stand Up To Cancer series, Don't Look Down. 

Since then she has grown her career exponentially, amassing over 3million followers on TikTok and 359k on Instagram. 

Most recently she worked as part of Channel 4's Paralympics presenting team, joining the likes of Vick Hope, Rose Ayling Elis and Ellie Simmonds in Paris. 

Earlier this year, Fats announced her engagement to photographer Alan Laszczak. 

Alan also has shares his life on social media, mainly produced content revolving around his fitness journey as someone who lives with cerebral palsy.

The couple had been dating for four years before they took the next step in their relationship in May and Alan got down on one knee.

Sharing their joyful news on her Instagram, Fats revealed that Alan asked her to marry him on beautiful beach in Thailand.

In the post she wrote 'Alan proposed! And I said yes!!!

'From the day we met I knew you were my person. Over the last 4 years you have changed my life for the better. I can’t wait to be your wife' followed by a love heart emoji and crying face emoji.

Alan also took to his own Instagram to share the happy news writing 'Only gone and popped the question and she said yess!!

'I love you with all my heart you are my soulmate, I’ve known it for a while now and just had to take action, this day turned out perfectly I’m gassed I can wait for the wedding and our bright future together!' Speaking about their relationship on Loose Women, Fats said: 'He's amazing, he's a gentleman. Everything I want in a man. We both have a disability so we understand each other. I love to be on camera, he loves to be behind the camera, so it works.'
