The actress tells Ellen DeGeneres that she's A-OK with it, too!
Alley says that True and his girlfriend have been dating for roughly a year, and she's perfectly fine with his plans.
She tells Ellen, "I feel good, because they're really in love. True's very ... he's got a level head. He's a good guy. He's very monogamous, and he's very sweet with her. You know, 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. So I think if somebody's in love and wants to be married, then let them be in love and get married."
