Bruce Willis wears GaGa-inspired meat hat

Bruce Willis paid homage to Lady GaGa's meat dress on last night's Late Show With David Letterman.

The Red actor took to the stage for his interview yesterday wearing a hair-piece made entirely from ground beef.

"You've dyed your hair?" questioned Letterman. "No," replied Willis. "This is all natural... It's a meat hair-piece inspired by GaGa... Huge fan of GaGa."

He went on to say: "It's 100% ground beef sirloin. Top shelf organic. Showering isn't a problem; I took a shower a couple of hours ago. Lather, rinse, repeat and tenderise..."

Willis asked Letterman if he was hungry before producing some salt and pepper which he sprinkled over his head. He then offered Letterman a fork and told him to "dig in carefully" which the host did, scooping up a small portion of meat and eating it.

GaGa hit the headlines when she wore her controversial meat dress, made entirely from raw meat, at the MTV Video Music Awards last month. She previously donned a bikini made from meat for the cover of Vogue.
