Michael Ausiello reports that Laura Prepon has signed on for a 5-episode stint on “How I Met Your Mother.”  Yes, you know who she is…Hot Donna from “That 70’s Show!” (Love that show by the way…)

Allow me to show you a picture for reference:

Ausiello writes: “Prepon’s alter ego — Ted’s squeeze through high school, college and then some — is said to be as snooty as she is beautiful, and notorious for cheating on her lovers to avoid having to explain why she’s dumping them.”

I didn’t watch “October Road” (way too girly for this guy), so I’m excited to see what Prepon can bring to the Ted-Mosby-table. So far, most of the celeb appearances on HIMYM have been quite excellent (Sarah Chalke…hell, even Brit’s episodes were good!).
