Casey Affleck Not Attending Bennifer Nuptials — Why?

Ben Affleck and his brother Casey have always seemed close, so why is Casey still in L.A. while other friends and family of Ben and Jen are arriving in Georgia to celebrate their wedding festivities?

TMZ reports that  Casey was spotted in Los Angeles on Saturday morning, seemingly too late to make it to Georgia to share in his brother's big day.

A pap bluntly asks, "How come you're not at your brother's wedding today?"

Though the pap and the outlet seem to think Affleck mumbles something about falling asleep in response, it also sounds like he is mumbling he has "other things" to do.

"Today is your brother's big day! You're an Affleck!" the pap exclaims, but Affleck quietly thanks him and drives away from the Starbucks where he'd been spotted.

A source later told People Casey's absence was due to "family, parental obligations."

Meanwhile, while Casey was interacting with the inquisitive pap, Ben and Jen were already in Savannah, as wedding preparations were in full swing at Ben’s Georgia estate.

Mama Affleck injured herself, but was released from a local hospital, ensuring she wouldn't miss any of the good stuff!

DailyMail.com posted an aerial view of the Hampton Island property, where trucks were making deliveries and tents were going up.

The estate was featured on HGTV’s “Fantasy Open House,” and Ben, J.Lo and their blended family of five children are reportedly staying in the so-called “big house.”

“Extra” Special Correspondent, Page Six’s Carlos Greer says the A-list guest list included Matt Damon and more.

Carlos added of the ceremony, which "ended with a kiss" on Saturday, that it was "supposed to be an intimate celebration for family and friends.”

Sounds like mission: accomplished!

Guests wore formal, all-white attire for the ceremony on Saturday, which took place a couple of hours before sunset. It had reportedly been in the planning stages for four months.
