The former Disney Channel star included the NSFW photo in a "dump" of other pics she shared to Instagram this week ... which included a number of pouty selfies, several candid moments and a couple sweet snaps of her man. (Hint: This actress-turned-pop star is set to get married!!!)

Think you have an idea of who this stunning A-lister might be???
