Jane Seymour has some personal insight into the strained relationship between Kate Gosselin and her Dancing with the Stars partner, professional dancer Tony Dovolani.

“I danced with Tony. I know what she’s going through,” Seymour, 59, tells PEOPLE at the New York Gen Art festival’s premiere of her new film, Waiting for Forever.

Seymour was paired with Dovolani three years ago when she was a contestant on season five of Dancing with the Stars.

She finished in sixth place after weeks of competing despite several health and personal issues, including a bout with food poisoning and the death of her mother.

“Tony’s tough,” says Seymour. “There were a lot of tears.”

Still, Seymour stops short of picking a favorite celebrity competitor from this season saying, “I’m rooting for everyone. I just root for the show.”
