Barbara Hershey was a cougar before cougar was cool. She snagged Naveen Andrews, of LOST fame on the set of Drowning on Dry Land, an indie film obscurely made in 1995. Although no one has ever heard of the film, the pheromones were flying and the couple were a fixture until 2005.
They split and Andrews, who is 21 years Hershey's junior, took the split as an opportunity to sew his wild oats. He became a baby-daddy, before reuniting with Hershey.
The couple remained glued at the hip, until six months ago when they called it quits.
