The group spent much of last night at Jako London, a private hire venue in High Street Kensington, before arriving separately at AJ’s cousin’s flat, despite not being allowed to mix in other households.
AJ, 26, and Abbie, 23, arrived at around 11pm and were seen leaving at around 1am.
London is currently under Tier 2 restrictions, meaning that people can only meet socially with friends and family indoors if they have formed a support bubble or live together, unless a legal exemption applies.
It is not known whether AJ is in a support bubble with his cousin, but he visited the flat with his girlfriend and others were also seen arriving before they left.
In high alert areas, support bubbles can be formed with only one household if you are the sole adult in your home, you live with someone with a disability, you live with a child who is under one or you live with a child who is under five with a disability.

Those who break the rules can be given a fixed penalty notice of £200 for the first offence, doubling for each further offence up to £6,400.
AJ was pictured wearing a white shirt paired with black trousers and a smart pair of shoes as he held hands with Abbie, who donned a belted leather dress, long coat and high heels.
The couple were also seen earlier this month enjoying a date month in Covent Garden with AJ sporting a black jumper along with a pair of dark grey jeans.
The TV star, who finished in sixth place on this year’s I’m A Celebrity… Get Me Out Of Here!, also dressed in a grey bomber jacket while he wrapped up further with a scarf while going for a romantic stroll with his other half.
Abbie wore a plaid mini shirt dress with black boots for her date with AJ with the pair donning face masks as they climbed into a taxi.
It follows MailOnline revealing that the former Strictly star treated Abbie to gifts and booked her a romantic weekend away following his Castle stint.
The dancer bought Abbie roses, perfume and candles that were delivered to her while he competed in gruelling trials for the ITV show.
Professional dancer Abbie, who believes AJ is ‘The One,’ said she had been ‘going crazy’ without her boyfriend by her side during his stint in the Welsh camp.

She previously told MailOnline: ‘I am so desperate to see him – I am going crazy I feel like I have been lost without him.
‘All I want to do is hug him and kiss him – it’s been too long now! I definitely can see he is missing me.
‘While AJ has been in the castle he organised some gifts for me that I’d have during his time in there to show he was still thinking of me.
‘He has booked Soho Farmhouse so we are going there in December for a couple of nights so I’m really excited for that.
‘He was so cute and very, very romantic, I got some gorgeous roses and candles and perfume as well.’
