Neil Jones' girlfriend Luisa Eusse reportedly cheated on the professional dancer just days after he went back to work and joined Strictly's quarantine bubble.
The Columbian dancer, 23, is thought to have met Spanish student Daniela Becerra, 20, while on a night out at private club Cirque Le Soir in London's Soho.
After partying the night away at the venue, Luisa is said to have invited Daniela back to Neil's flat where they 'had sex', reports The Sun.

A pal of Daniela's told the publication: 'She [Luisa] asked me if I wanted to go to her bedroom. She cheated on Neil with me. We had sex.
'We were in the bedroom for an hour — a long time. It wasn't a quick ten minutes.'
The friend also claimed that Luisa revealed her relationship with Neil after the deed was allegedly done, with the dancer saying she was 'married'.
MailOnline has contacted Neil and Luisa's representatives for a comment.
After finding out Luisa wasn't single, performance art student Daniela is thought to have been shocked and wanted to leave, with her going home around 6am.

After the wild night of partying, Daniela allegedly told pals: 'I had no idea who Neil Jones was. I follow the Spanish version of Strictly Come Dancing, not the one here.'
The friend also alleged that Daniela and Luisa started getting close during a game of spin-the-bottle at Cirque Le Soir.
They claimed that on Luisa's turn she had to kiss someone and chose Daniela, with the pair then 'flirting with each other the entire night'.
After leaving the club, it is claimed that Daniela and Luisa travelled back to Neil's flat in a white Tesla while her pals took an Uber.
