Will Smith & Jada Pinkett Smith: We see them out as a family unit more than most, and with one of those kids being from a previous relationship, they're really a great example of the New American Family.
Faith Hill & Tim McGraw: Both wildly successful in the same field, and completely gorgeous, yet seemingly down-to-earth.
Sarah Jessica Parker & Matthew Broderick: Child stars grow up to find one another and go through some serious career ups and downs (See how that works Madonna & Guy?).
Amy Poehler & Will Arnett: The couple that laughs together stays together, right?
Susan Sarandon & Tim Robbins: Marriage isn't the only way to commit, and as far as Hollywood relationships go this one's the motherlode. Super liberal (and willing to put their mouths and money behind it) and I don't really know who is more successful. Honestly, if they ever break up, I might never recover.
