Married At First Sight stars Gabrielle Bartlett and Sean Donnelly are reportedly 'sleeping together', according to fellow MAFS star Nasser Sultan.
The fiery personal trainer appeared on the Kyle and Jackie O Show, and shockingly said: 'Gab is sleeping with Sean from Adelaide.'
'Apparently she flew down to see Ryan's gig and [Sean's ex 'wife'] Jo [McPharlin] caught them in the hotel room. The story will come out today I guarantee it.'
'I tell you, she always had a soft spot for Sean because he used to come into our room to have drinks,' Nasser added. 'It's one of those things like 'Come on Sean, go home, it's two in the morning. But him and her used to stay up quite a while.'
Gab and Sean are both yet to comment on Nasser's claims.
