The graffiti-strewn subway, situated in Belfast, has become something of an iconic landmark among fans, with AC12 meeting there numerous times since the show relocated to Northern Ireland in 2014.

Captioning the playful clip, which ends with the three stars bursting into laughter, she wrote: ‘Best friends!’
