Blake Lively & Ryan Reynolds

These newlyweds met on the set of the disastrous “Green Lantern,” but awful reviews couldn’t keep this insanely sexy couple from falling head over heels for each other. RyRy’s divorce from Scarlett Johannson was finalized just last year, but by September 9, he skipped the engagement and secretly tied the knot with the “Gossip Girl” beauty 10 years his junior. We’ll see if they last longer than Reynolds’ last marriage — just don’t make a sequel!

Jennifer Garner & Ben Affleck

This couple first met on the set of “Pearl Harbor” but didn’t date until they made 2003’s “Daredevil” together. Both bad movies, but Ben and Jen are a Hollywood golden couple. They’ve been happily married since 2005, which is long enough that some people have forgotten Ben’s engagement to the other Jennifer (Lopez, with whom he made the awful “Gigli”). The Afflecks have three gorgeous kids: Seraphina, Samuel and fashion icon Violet.

Miley Cyrus & Liam Hemsworth

We’ll call them a “good couple” because they seem to really like each other and have lasted a while, considering their adolescence. And Liam stuck by Miley’s side during her Draco Malfoy haircut fiasco. Hannah Montana met her hunky Aussie fiancé on the set of “The Last Song,” a catastrophically sappy Nicholas Sparks adaptation. We don’t approve of their youthful engagement or believe in its permanence, but we get it, Miley: anyone would volunteer as tribute for Gale.

Angelina Jolie & Brad Pitt

For being Hollywood royalty, Brangelina were brought together by a film that was pretty blah. Most people saw 2005’s action rom–com “Mr. and Mrs. Smith” to see the movie that split up Brad and Jennifer Aniston. You would’ve hoped the flick that caused the breakup of the century would’ve been “Fresh” on Rotten Tomatoes. At least “Wanderlust,” the comedy that brought Jen her new fiancé Justin Theroux, was actually funny.

EXCEPTION: Good Movie, Good Couple: Emma Stone & Andrew Garfield

“The Amazing Spider–Man” was a commercial and critical success this summer, with the highest box office gross behind other superhero films “The Avengers” and “The Dark Knight Rises.” While Tobey and Kirsten’s series feels not too long ago, Andrew and Emma’s onscreen chemistry made up for the superfluity of the film. Off–screen, the trendy New York couple was recently spotted holding up pieces of cardboard to block their faces from the paparazzi — with charity organizations Sharpied on them. Sigh.

EXCEPTION: Bad Movie, Bad Couple: Kristen Stewart & Robert Pattinson

These two are an exception to the trend, and in all the wrong ways. The five “Twilight” films have birthed this loathsome couple. Onscreen vampire drama and indecision translates to infidelity for the lip–biting Stewart, who cheated on Pattinson with the (not even attractive) director of “Snow White and the Huntsman.” Whether or not they’re back together at this moment, shame on you, K–Stew.
