However, the former WWE Superstar is open to working with her husband again for a potential project."Oh my gosh, I think the key to being married for 12 years and the key is we don’t work together. But yeah, it’d be really cool. ‘Never say never’ is what I say to all the things when people ask me where I’m going to work. But yeah, he's a really good writer. He's a great artist. He's killing right now - acting and wrestling," Lee said.Lee has always been linked to a potential WWE return, including the Royal Rumble and Evolution, which sadly didn't materialize.
