My guess would be the lad from Stoke who likes Angels and Candy who has just become a Dad
That's who I always thought people were referring to when they talked about Dec and "the fat dancer". However, it occurred to me that his equally prominent bandmate wasn't always in top shape so maybe they meant him.
I followed that sexy actor who has the awesome fit body in eastenders programme the day before yesterday,and if hes not gay,with that mince Im a monkeys Uncle.
I don't think he's sexy myself but are you referring to the actor playing the character with a name like a baby kangaroo?
