Pick a branch of the entertainment industry, any branch, and you’ll find stars who are as inextricably linked as is their animosity toward one another. Joan Crawford and Bette Davis. David Lee Roth and Eddie Van Halen. Bruce Willis and Cybill Shepherd. Gargamel and Papa Smurf. The list goes on and on but curiously does not include the pair who are the subject of today’s blind item.

Who are they? And how have they kept their mutual hatred a secret?

That’s for you to figure out. But what I can tell you is that when they worked together years ago, it was to great acclaim — so great that a lotta folks have been hoping they’d reteam ever since. Recently, a small-screen opportunity arose that would’ve allowed for exactly that to happen, only the ex-castmates said, and in no uncertain terms, hell to the no. They both still took the gig, mind you, they just insisted on never being made to act opposite one another.

I’d try to build in an extra clue or two, but frankly, the thought of them hating me half as much as they do each other terrifies me. And I’m not sure I could learn to sleep with one eye literally open. But you guys feel free to guess away. Though I won’t tell you if you’re right, I might let at least a few of you know if you’re wrong.
