Put a ring on it: These two lovebirds once dated for a few years back in the '90s. When they were both single again 10 years later, Nicolette and Michael reconnected. Then on a trip to the Bahamas in 2006 they got engaged and sang a duet together, so it seemed like all systems were a go.
Cancel the cake: Alas, by 2008, the romance was dead and the engagement off. Perhaps these two should have realized they'd split once for a reason.
