Kirstie Alley appeared on The Ellen Degeneres Show to talk about her new show Kirstie Alley's Big Life, but ended up chatting about her 17-year-old son's marriage.

True Stevenson is marrying his high school sweetheart - while he's still in high school. Kirstie said, "I feel good because they're really in love." She also said, "I was married when I was just 19 years old and that didn't work... Then I was married when I was 30 years old and that's when everyone said you should get married and that didn't work. So I don't think I'm an expert on the subject."

"I think if somebody's in love and wants to be married then let them be in love and get married."

True is Kirstie's child with Parker Stevenson, who she was married to for 14 years.
