Strictly Come Dancing bosses have launched an investigation into an event company over £500 weekend parties featuring the show's stars.
Nadiya Bychkova, Giovanni Pernice and Kai Widdrington - three of the show's professional dancers - all appeared in an advert for a private travel company promoting a dance-weekend on the travel firm website.
Although Strictly-themed events are exceptionally popular across the country, none are officially associated with the show and the BBC has strict rules about their stars and what promotional work they can carry out - with presenter Stacey Dooley and Nick Knowles being punished for breeches in the past.
