Singer Michael Bolton and his fiancee Nicollette Sheridan are teaming up to record an album of duets. The Desperate Housewives star has no previous musical experience, but is venturing into pop after encouragement from Bolton. She says, "I am such a shy singer but Michael has made me more confident and my voice has grown. We're planning an album of duets. "You might think its madness but we like the way our voices blend."
