When you think hot Hollywood abs, you think … Jenna Fischer? That frumpy chick from “The Office”? Yup, that’s her, and she’s looking mighty good. We’re not talking world-class abs or anything, but you gotta admit, you didn’t think she had this in her, right? I sure didn’t. Here she is in a bikini on the cover of Shape magazine. I’ll swap the pic with something better/bigger when it becomes available. Until then, admit it, you’ll never watch “The Office” the same way ever again.
