Those who remember Donna Air from the 90s will recall a pretty child actor and an MTV presenter with a distinctive Geordie accent.
But it seems the former Byker Grove star has shocked everyone by ditching her Newcastle dialect and attempting to speak posh on BBC's Celebrity MasterChef.

And the internet wants to know why...

Naturally, the internet has loads of theories - the most prominent one being her on-off relationship with the Duchess of Cambridge's brother James Middleton may have something to do with it.

And somehow her accent is drawing bizarre parallels with Brexit.
Donna Air's accent has had a bit of a Brexit itself..?? Geordie lass meets Made in Chelsea crew, bizzare!! #masterchef

Donna air is putting on that much of an accent she sounds foreign she'll be deported if she keeps going on like this #masterchef

This person seems to have particularly strong words of advice for the TV personality.
Can't cope with Donna Air on #masterchef stop over pronouncing everything. Be true to yourself and speak normally

And this person wants to know how Donna managed to pull off such a feat.
I've been away from Dundee for 22 years but still have the thickest accent. How has Donna Air completely lost her Geordie one? #MasterChef

But despite her best efforts in the kitchen, Donna didn't make it to the semi-finals - losing out to Tommy Cannon and Alexis Conran in the final challenge.
