The 32-year-old actor - who is best known for playing teacher Will Schuester in `Glee` - relaxes in his home without wearing clothes, but admits it can be tricky because fans are often outside his house.
He said: "For me, the most absurd fans are the ones who camp outside my house. It`s strange.
"Luckily, I have a big gate and it`s very protected, but it`s a little scary as I look around for cameras before I sunbathe in my yard.
"I love walkingaroundnaked in my house. Who doesn`t? But when I walk by the window I have to make sure there`s no one outside."
As well as meeting fans by his home, Matthew revealed he often has bizarre encounters in unusual public places.
He explained to Now magazine: "The oddest place I`ve been recognised was n the urinal. A guy came up to me and said, `Hey, what`s up dude?` "
When filming `Glee`, Matthewloves working with Jane Lynch, who plays Sue Sylvester.
He said: "She`s become my best friend from the show, which is why our relationship works so well.
"Jane makes me laugh constantly. It`s hard doing scenes with her as she`ll throw in weird facial expressions that make me howl.
