When you have a name as unusual and unique as 'Chord Overstreet', you'd expect people to be able to identify you quite easily. Unfortunately for Overstreet, he was born into the same world as Austin Butler, at around the same time. The windswept blond hairstyle that both men go for doesn't really help people tell them apart, either.
They even have similar hobbies and routes into stardom. Both of them came to prominence through the world of acting but are actually musicians at heart. Overstreet used 'Glee' as a vehicle to bag himself a recording contract, and although a lot of people Butler was also part of that cast, he wasn't. He's appeared as a singer within "iCarly" but is yet to release anything in his own right. If you need a pointer in telling them apart, Overstreet has the fuller face, whereas Butler still has younger, boyish features, although both of them are pin up icons for teenage girls.
