17. Will Smith & Jada Pinkett Smith
Will and Jada are considered one of Hollywood's most powerful and stable couples, but they fell several spots on our list this year. Why? Although Jada's starring in the new series HawthoRNe, Will didn't star in any movies in 2009, and rumor has it he was a bit domineering on the set of her show (he's a co-producer). Could there be trouble brewing?
