Coronation Street fans spotted a big problem with Sean's party plan on tonight's episode.
Tonight saw Sean host a make-up party at the bistro to promote his new cosmetic business venture.
Sean asked several members off the street to come to the party, but it wasn't long before viewers spotted a big problem with his plans.
Manchester, where the ITV soap is filmed, is currently in lockdown along with the rest of England with major restrictions on social interactions.
People from different households are unable to meet together and all hospitality venues are closed.
And many viewers took to social media to point out the blunder.
Helenpat said: "Sean wants to have all the neighbours over for a party in the middle of a pandemic."
Shaky said: "So Sean wants to host an Avon party...he'll need to adhere to the rule of six though."
And Bradley Coombes said: "Sean wants a party in lockdown.. last week it was a football match."

It's not the first time Sean has gone against the government's coronavirus lockdown rules.
Last month Sean agreed to take his son Dylan to watch Weatherfield County play, rushing around the street to get the best tickets possible.
However, Corrie fans pointed out that the father and son trip to the game wouldn't be possible because of Covid-19 restrictions.
