Titanic is back in theaters today! It's hard to believe that it was fifteen years ago that the iconic movie first crashed (sorry, bad pun) onto movie screens.

In honor of the film's re-release and the adorableness that was and will forever be Leonardo DiCaprio, we're taking a look at the biggest movie star heartthrobs -- and the movies that catapulted them to stardom -- from Leo back in 1997 all the way through today!

Ben Affleck isn't just totally hot, but he's a family man, too, which makes him that much more loveable! With two daughters, Violet, 6, and Seraphina, 3, and another child on the way, Affleck has opened up to People Magazine about how his children inspire him to do good.

And that's just what he's done! Affleck recently returned from his eighth trip to the poverty-stricken African Congo, where he set up the Eastern Congo Initiative back in 2010, and says his daughters are the reason he started the non-profit organization.

Jennifer Garner is pregnant with baby number 3, and while she is at home resting up, her hubby Ben Affleck is dominating parent-duty!  The proud dad took the couple's two daughters, Violet, 5, and Seraphina, 2, to the Pacific Palisades Farmer's Market on Sunday afternoon.

Affleck stayed close to his girls, carrying Seraphina and holding Violet by the hand, as they picked up some fresh fruit at the market.  But what's even cuter?! They picked up a bouquet of flowers to bring home to Mom!
