AMERICAN IDOL cutie DAVID ARCHULETA will guest star on the hit Disney Channel series HANNAH MONTANA this Sunday (5/3). Titled ‘Promma Mia’, the episode has MILEY CYRUS agreeing to go to the prom with the school nerd and then bailing on him when the chance to record a duet with ARCHULETA comes along. The episode will include (natch) the MILEY/DAVID duet, ‘I Wanna Know You’. When we spoke with ARCHULETA recently, he talked about how crazy his days have become and it looks like it’s still going on.
