Looks like Kathy Griffin didn't get the memo.
Tyra Banks is taping the entire season of her talk show with her natural hair -- but Griffin donned one of Banks' old weaves for an appearance that airs Sept. 21.
"You were supposed to wear real hair!" Banks says.
"I stole this from your room," replies Griffin. "I bet this is, like, $5,000."
Says Banks: "More like $50."
Griffin jokes that she's "very nervous about having to wear my real hair on the show.
"I usually enjoy the magic hair [extensions], as the gays call it," she quips. "I feel naked and like I should make a sex tape as long as I'm naked."
