Miley Cyrus forgot to wear her pants in this pre-Halloween celebration photo.

The 19-year-old bride-to-be tweeted this photo of herself and 12-year-old sister Noah on her Pheed account Tuesday. The caption simply read, “boo.”

Speaking of boo, Miley admitted to Chelsie Handler that she is infatuated with Honey Boo Boo. During her stop on “Chelsea Lately” to plug her forthcoming album and her guest gig on “Two and a Half Men,” Miley focused her attention for a bit instead on Alana ‘Honey Boo Boo’ Thompson and family on “Here Comes Honey Boo Boo.”

She even revealed that she made changes to her home so she could watch and better hear the 7-year-old. . “I put in a home theater in my house, and then it wasn’t quite loud enough so we got sub woofers so I can really hear her extra loud,” Cyrus said. “So when I hear her, ‘Holla for a dolla!’ The whole house shakes.”
