For years Matty McLean has had a go-to fun fact about himself locked and loaded ...
He has a third nipple!
However, this interesting anomaly has always just been a self-diagnosed hunch.
So Matty & PJ on The Hits Drive decided to get an expert to weigh in.
Dr Sean joined the hosts to give his two sense on the matter - and what he had to say left both Matty & PJ completely shocked!
After examining photos Matty had sent Dr Sean, he concluded that yes, the third nipple in question is in fact a nipple!
But what's more - Matty also has a FOURTH nipple!
Watch Matty & PJ's hilarious reaction above.
