Jack Webb's marriage to Julie London...

They had children together. They worked together afterwards. Jack was good friends with Bobby Troupe. He remained in their daughters lives after the divorce.
Webb had a reputation as an workaholic, a hard drinker and mean drunk. He did remarry.

There are stories of his "Dragnet " badge getting him out of dui tickets in California.

If he was gay, it would have been big news to his wives and girlfriends.
