Ben Affleck spoke to a reporter about his sobriety on Sunday after the actor appeared to be inebriated at the UNICEF Masquerade Ball in Los Angeles the night prior.

Its a slip, but Im not going to let it derail me, Affleck said. A rep for Affleck did not immediately respond to HuffPosts request for comment.
