Lauren Conrad guest stars on Family Guy.

She may look like she's got the acting thing down pat on her reality show The Hills, (because we all know that show is scripted) but Lauren Conrad is the first person to admit that acting isn't her thing. (Really? Like I didn’t notice that on your “show”)

In fact, for an upcoming episode of Family Guy (in which she guest stars) the starlet tells OK! she had to hire an acting coach!"I hired an acting coach for the day to get me through it because a lot of the lines later on in the episode that I did are very complicated," she tells OK!. "There are a lot of facts and big words, and I had to say it as if it was coming to me very easily instead of just reading them.

I actually had to research some of them!"Luckily for Conrad, her acting coach saved the day! "My coach that I was working with told me if I really understood what I was talking about, it would come through a little more true."Very true, LC, very true!Catch Lauren's guest appearance on Fox's Family Guy when it airs Sunday, May 3!
