Miley Cyrus will be appearing in a cameo role in the Sex and the City sequel. In what appears to be a very short scene, Miley wears the same dress to a red carpet event that Kim Cattrall’s character buys to look "hot and young." In the script, Mario Cantone’s character Anthony responds by exclaiming, "Mother of God: She is wearing the same dress as Hannah Montana."
