Beverly Hills, 90210 star Tori Spelling knew it was time to have a good hard look at her first marriage when she cheated on her then-husband with her new man the first night they met. The actress was married to writer/actor Charlie Shanian when she met Dean McDermott and fell madly in love with the Open Range star.

Spelling had no regrets about sleeping with McDermott hours after she first laid eyes on him - and that made her realize her brief marriage was in trouble. She says, "After it had happened I didn't feel any regrets and I thought, `I'm madly in love with this man that I've just met... and this is forcing me to really look at my marriage."

Pregnant Spelling and McDermott wed in 2006, shortly after the actress' divorce was finalized.
