Someone on the main board is hinting Mark's partner is someone from 90210. I wonder if it's the new series or the old one

I might be content if it's the old version, because I could possibly get my wish that Mark wouldn't last long with someone from that show. Gabrielle Cartieres isn't as well known as Tori Spelling (who's said she wants to do the show with her hubby), but Tori isn't really as likeable as she once was, and Shannon Dorohty had a bad reputation from her former castmates on both 90210 and Charmed. I quit watching 90210 halfway through the original series, but the only other ones I can remember being on the show besides those 3 and Jennie Garth are Tiffani Thiessen and Hillary Swank, but I know she wouldn't even be a possibility. And she'd be too tall for Mark I think.
I don't watch the new version of the show. Some of my co-workers do and love it, and I could see the show maybe wanting to try and lure in the younger demographic by casting from there.
I don't begin to understand the technical aspects of the dances, but since I don't think the judges base their votes on that as much as they like to say they do, I don't feel bad getting mad when I think someone pulled a dance off and the 3 Stooges say they got it all wrong

Louis choreographed that number; he's just amazing. The dance Lacey choreographed for the girls just seemed more like camera mugging and posing, but Louis seemed to do a really good job with the dancing and getting all the pros involved and showcasing them.
