They also later starred together in the film "Ali" in 2001 and established the Will and Jada Smith Family Foundation, which focuses on youth educational projects and family welfare for charitable organizations in Baltimore and Philadelphia.

Their two children are also in show business: Actor Jaden Christopher Syre ("The Pursuit of Happyness" and "The Karate Kid" remake), and actress/singer Willow Camille Reign ("Whip My Hair"). Smith also has a son from a previous marriage, Willard Christopher "Trey" Smith.

Will on Jada: "Families are like a business. The key is one person having a vision of what it needs to be and being able to pull everyone together. That's Jada for sure."

Jada on Will: "I will throw my career away before I let it break up our marriage. I made it clear to Will. I'd throw it away completely."

Who is our next couple? One word: Brangelina ...

Mr and Mrs Smith

Brad Pitt and Angelina Jolie

Their characters tried to kill one another in "Mr. and Mrs. Smith" in 2005 and somewhere in between, the actors fell for one another. Although Brad was still married to actress Jennifer Aniston at the time, both Pitt and Jolie have denied any romantic extramarital affairs.

But there's little doubt the roots of Brangelina go back to that movie set.

Together the happy yet tired couple have six children: Maddox Chivan, (adopted from Cambodia, shared with ex-husband Billy Bob Thorton); Zahara Marley, (adopted from Ethiopia); Shiloh Nouvel; Pax Thien, (adopted from Vietnam); and twins Knox Leon and Vivienne Marcheline.

Pitt and Jolie were finally married the summer of 2014 in a private ceremony.

Brad on Angelina: "She is the love of my life."

Last up, we find out what happens when Danny Zuko settles down ...

John Travolta, wife Kelly

John Travolta and Kelly Preston

They found a strong attraction toward one another on the set of "The Experts" in 1989 but were in relationships at the time. Two years later, the two became experts on each other and tied the knot. Hey, who wouldn't fall for Danny Zuko?

The couple has three children: Benjamin Hunter Kaleo and Ella Bleu. Travolta and Preston also grieved when their son, Jett, died in 2009 due to a seizure at the age of 16.

Travolta has said "having kids gives a mandate to make your marriage work ... the kids are a big motivating factor."
