"Baldwin has a tattoo on his left shoulder of the initials "HM" for Hannah Montana. He got the tattoo after making a pact with Miley Cyrus that he would be allowed to cameo on the show if he had the initials tattooed on him. He revealed the tattoo to Cyrus at a book signing in Nashville, on November 10, 2008. To date he has never appeared on the show. He has since gone on record as saying that he regrets getting the tattoo."
