Actress Katee Sackhoff has a confession: She’s obsessed with TV personality Bethenny Frankel.

“She’s probably a kindred spirit of mine,” Sackhoff, who stars on the A&E series Longmire, said in a recent AP interview. “She’s my sister from another mother, [and] I’ve never met her.”

Frankel became famous as one of the cast members of The Real Housewives of New York City and two spinoffs. She has written several books and recently rolled out a talk show on Fox. Sackhoff says she follows her on Twitter.

“I’ve never met somebody in the public eye who speaks as honestly as I do,” Sackhoff says of Frankel, “and it’s refreshing because there are times where I question whether or not people can actually handle the truth or if they want it. I’m a very open book about who I am. I think it’s the only way to kind of touch people, and she’s done it. It’s pretty amazing.”

Sackhoff, 32, has had success playing women who aren’t shrinking violets.

She starred as Kara “Starbuck” Thrace on Battlestar Galactica, which made her a fan boy sex symbol. Now she’s holding her own as Deputy Sheriff Victoria “Vic” Moretti on Longmire, based on the best-selling mystery novels by Craig Johnson. The show airs its first-season finale 10 p.m. Sunday.

Sackhoff enjoys playing Vic.

“I love the fact that she walks into a room and she wakes you up. She’s loud, she’s fast and she’s great at her job, and she says things that she probably shouldn’t say and she does things that she probably shouldn’t do,” she says. “I think that she’s probably the closest that I’ve played to myself, which is really fun.”

Longmire made its debut in front of 4.1 million viewers, making it A&E’s top-rated original series premiere ever. It has been picked up for a second season.

“[The ratings are] four times what Battlestar used to get an episode. It’s a hit, and it’s really weird. I feel this fondness for it that I felt toward Battlestar.”
