It usually takes a while for a couple to truly be themselves with each other -- and that's doubly true for celebrity couples who met on TV or movie sets while playing entirely other people. But maybe that just made things even more interesting. Here are 10 who (as of this writing, anyway) are still together.
Ben Affleck & Jennifer Garner
The couple met while filming the 2003 movie 'Daredevil,' and Garner was already pregnant with the first of their three children when she and Ben wed in a 2005 Caribbean ceremony.
Brad Pitt & Angelina Jolie
By now pretty much everyone knows the story: Brad was married to Jennifer Aniston when he and Angelina met on the 2004 set of 'Mr. & Mrs. Smith.' Less than a year later, Brad and Jennifer split -- and he and Jolie (and their growing brood of children) have been together ever since.
Ashton Kutcher & Mila Kunis
Unlike most of the other couples on our list, it took this one a while to get together. After co-starring on the sitcom 'That '70s Show,' which ran from 1998-2006, Mila and Ashton stayed friends -- until finally taking it to the next level in 2012.
Nicholas Hoult & Jennifer Lawrence
Hoult and everyone's fantasy BFF met while shooting 'X-Men: First Class,' and split in early 2013 after dating for two years. But apparently they had second thoughts -- because word has it they're now back together.
Ryan Gosling & Eva Mendes
Ryan met Eva while they were filming this year's 'The Place Beyond The Pines,' and it wasn't the first time Gosling found love on a movie set -- he and previous girlfriend Rachel McAdams hooked up on the set of 'The Notebook.'
Stephen Moyer & Anna Paquin
The 'True Blood' co-stars started dating after the HBO series bowed in 2007, and wed three years later. Their fraternal twins, Charlie and Poppy, were born in September of 2012.
Channing Tatum & Jenna Dewan-Tatum
This is one couple who has the moves -- they fell for each other on the set of the 2006 dance flick 'Step Up,' had a 2009 Malibu wedding, and became first-time parents earlier this year.
Ryan Reynolds & Blake Lively
Reynolds was married to Scarlett Johansson in early 2010 when he and Lively met while filming 'Green Lantern.' But it wasn't until almost two years later -- a full year after he filed for divorce -- that the former co-stars got together. They quietly wed in September of 2012.
Olivier Martinez & Halle Berry
Halle's romantic history is certainly storied, but after meeting the gorgeous Oscar-winner on the South African set of 2010's 'Dark Tide,' the French-born Martinez must have decided to throw caution to the wind. The couple married in July of this year, and are currently expecting their first child together.
Justin Theroux & Jennifer Aniston
Theroux had reportedly been involved with his girlfriend for more than a decade when he met Aniston two years ago on the set of 'Wanderlust.' He and Jen are now engaged -- ironically making her the Angelina Jolie in this love triangle.
