CORONATION Street's Maria seems to forget that Ali Neeson is her nephew and falls into bed with him in upcoming scenes.
The unlucky-in-love hairdresser falls for the doctor's charms following several disastrous dates.
But fans have rushed to Twitter to point out that the pair were actually related.
"So is no one going to talk about the fact that Ali is Maria’s nephew through marriage? She was married to his mum’s brother and her son Liam is Ali’s cousin," one viewer tweeted.
And several other fans began commenting on the post, with one praising: "Thank you, finally someone else has said it it's not so long ago Michelle fell out with Carla because she was seeing him."
Another fan commented: "I have been saying this too … it even seems she's forgotten!!"
While a third joked: "Ooh yes …… but to be fair there’s nobody left she hasn’t already been with … only Roy maybe"
Maria is indeed technically related to Ali, as her previous husband Liam Connor was Ali's mum, Michelle's, brother.
This would make deceased soap star Liam Ali's maternal uncle, Maria his aunt through marriage and their son Liam Jr's cousin.
However this technicality hasn't stopped the Connor family before, as Carla, also Ali's aunt, enjoyed a steamy affair with him last year- much to Michelle's dismay.
And it doesn't seem to have occured to Maria either, as the pair are set to embark on a steamy romance of their own.
And fans of the soap have taken to Twitter to encourage the new relationship.
