“My one or two other marriages … weren’t so great, and they were quickie,” Doherty tells reporters recently at the Television Critics Press Tour.
“My heart goes out to her. I know that. And I also applaud anybody who gets out of something if it’s not working regardless of the terrible jokes and press that’s going to come at them.”
But the former Beverly Hills, 90120 star, who tied the knot with photographer Kurt Iswarienko in October, feels that she’s finally found lasting love.
“I truly, truly, truly believe in love, and I may have messed it up once or twice before. But, you know, I met Kurt, and the world sort of stood still for a second,” she tells PEOPLE. “He just instantly felt like my best friend. And I thought, ‘OK. This is different from what I felt before. So this one is going to stick.’ ”
The couple’s relationship, including their nuptials, will be chronicled as part of the upcoming WEtv reality series Shannen Says, which is set to premiere in April.
