Jennifer Lopez, Ben Affleck's Second Wedding, Awesome Wedding Dress, Photos

Jennifer Lopez and Ben Affleck made a pretty spectacular entrance to their second wedding ceremony Saturday night … he looked great but she … well, wow.

J Lo wore a pretty magnificent white gown with a long, long train — approx 20 feet — as she and Ben got ready for the march down the aisle.

It looks like Ben and Jen may have arrived by boat … they greeted friends and family in the wedding party on the dock.

It was a white-themed affair … with the exception of Ben’s black tuxedo pants.

Their kids were on hand for the ceremony and the bash that followed at Ben’s $8 million home in Savannah, Georgia.

Ben and Jen couldn’t keep their hands off each other as they took photos with the wedding party.

Among the guests … Matt Damon and wife Luciana, Kevin Smith and his wife Jennifer, Jason Mewes and his wife Jordan, titan talent agent (and Lauren Sanchez‘s ex-husband) Patrick Whitesell and wife Pia.

The officiant was podcaster Jay Shetty … a life coach who is kinda new age.

There was a big tent for the shindig, which as of this post is still going strong. There’s a fireworks show in store for the guests later in the evening.
