On Friday, Jesse James stepped out for the second time since his affair scandal broke earlier this week.

Still wearing his wedding ring, the somber-looking biker, 40, dropped his kids off at school.

A day earlier, he publicly apologized to wife Sandra Bullock, 45, and his kids for any "pain and embarrassment" he has caused.

He did not address specific claims that he had an 11-month affair with tattoo model Michelle McGee.

"I am truly very sorry for the grief I have caused them," he said. "I hope one day they can find it in their hearts to forgive me."
