Laura Prepon is one of my favorite actresses. Not because she’s the greatest actress that ever lived (not that she’s bad, mind you – I enjoy her work), but she’s my kinda gal.

Heck I watched “October Road” just because she was on it.

Anyway, Ms. Prepon will be appearing on 2 episodes of “How I Met Your Mother” according to TV Guide.

She will be playing the character of Karen who is an ex of Ted’s. There’s no word yet on when her episodes will air, but expect to see her in the next month or so.
