What a night! The Justice League premiere brought out half of Hollywood Monday night, and all eyes were on newlyweds Jason Momoa and Lisa Bonet. They revealed recently that, though they've been together since 2007, they didn't officially marry until October, in a backyard wedding at their Topanga Canyon home in LA.

But that wasn't the only story on the red carpet ... a recently rehabbed Ben Affleck showed off a buff frame and a big smile and co-star Amber Heard, recently separated from boyfriend/Tesla mogul Elon Musk, looked stunning and single at the Hollywood & Highland premiere.

Israeli beauty and Wonder Woman star Gal Gadot sparkled in gold lame and showed some serious leg ... and in the lots-a-leg department, Ludicris' wife also rocked a high-slit dress with her rapper/actor hubby. And then there's Henry Cavill ... ahhh ... hi mustache isn't our fave, but dang, he's so cute!

So for those thinking about seeing the sure-to-be-blockbuster this weekend, here's the haps: "Fueled by his restored faith in humanity and inspired by Superman's selfless act, Bruce Wayne enlists newfound ally Diana Prince to face an even greater threat. Together, Batman and Wonder Woman work quickly to recruit a team to stand against this newly awakened enemy. Despite the formation of an unprecedented league of heroes -- Batman, Wonder Woman, Aquaman, Cyborg and the Flash -- it may be too late to save the planet from an assault of catastrophic proportions."

That's what IMDB says, anyway. Watch the trailer and then hit the theater tomorrow!
