Deny, deny, deny. Photos of what looks like short-haired Miley Cyrus smoking a big ol' blunt have surfaced online. But the singer/actress, who has a lot of young fans, tweeted that it's not her.

Her proof? She doesn't have an Instagram account, which is where the photo was generated.

Well, the photo sure looks a whole lot like Miley Cyrus, even though she is surrounded by a cloud of pot smoke. It's not like we can mistake her for Snoop Dogg. She's also wearing an engagement ring, and we all know Miss Miley is betrothed to actor Liam Hemsworth.

Sorry, we're not buying it, Hannah Montana.
