Pop Goes The Culture.

Who knew?

It’s Halloween weekend and who can forget the really bad (and I mean, really bad) Halloween-themed movies from our childhood that played non-stop on Disney?

I just found out an interesting connection: apparently Blake Lively of Gossip Girl is step-sisters with Robyn Lively who played the lead character Louise Miller on the cheesy 80’s flick, Teen Witch.

Remember that movie? Here’s a refresher:

Robyn (L) played the red-head popular wannabe in Teen Witch and Blake (middle) is today's "It Girl" are pictured here at the 2010 Spike TV Scream Awards.
