Who is this? She's an actress who appeared in one episode of That 70's Show (season 1, episode 12, "The Best Christmas Ever") and she looks really familiar.
She's one of three girls who make a one-time appearance in this episode, but none of them are named except in the credits, so I know the actress is one of the following three, but any google or image search I pull up hasn't been very helpful.
Her name is either "Sarah Hawkins", "Heidi Marshall", or "Megan Paul" but beyond that I am having no luck.

On a side note (and probably easier to answer) she looks a lot like another actress, but I can't think of the other actress' name or where I've seen her. If you can at least give me the name of the actress this one looks like, I'd be greatly appreciated.
