David Boreanaz - star of Bones and Angel - has admitted being unfaithful to his wife of nine years, Jamie Bergman.
The actor opened up about the affair claims after a woman he was involved with hired a lawyer and threatened to go to the media.
"(My) marriage has been tainted with my infidelities," the actor tells a US magazine. "I just want to be open and honest. I was irresponsible."
