Matthew Morrison reveals his washboard abs secret!

Hey, I don’t need much of a reason to post pics again from Matthew Morrison’s Details photo shoot from last fall.

We already knew the Glee star was a hunk but these photos of his ripped physique really took our breath away.

“I had to have a six-pack on show,” the 32-year-old Matthew tells U.K.’s Sunday Mirror. “The potato acts as a sponge and your body literally shrinks and gets ripped and tight.”

So what happened after the photo shoot?

“Afterwards I ordered two pizzas and pasta!” he says.
