Casey Affleck did not attend older brother Ben Affleck's star-studded wedding to Jennifer Lopez this past weekend in Riceboro, Georgia.

The brother of the groom, 47, was spotted in L.A. on several occasions just hours before Ben's big day.

In video obtained by the New York Post, Affleck was spotted in Los Angeles Saturday morning and was asked why he wasn't already at the three-day extravaganza. 

Through a mumble, the Academy Award-winner said, "I have other things."

However, a source close to Affleck says that "unfortunately because of family, parental obligations at home," he will be absent from the big bash, according to People.

Affleck has two sons, Indiana, 18 and Atticus, 14 with ex-wife Summer Phoenix.
