In the May 3 episode of Fox's animated classic Family Guy, Lauren Conrad's animated self get busy with Brian Griffin - he's the dog, of course - but she also reveals that beneath that bubbly exterior, she's smarter than the average starlet.

Only on Family Guy.

Lauren told E! of her gig on the long-running series, "The idea is that they make fun of me for being dumb and then discover that I am actually a genius ... and that [Lauren Conrad is] a character I play [on TV], because America likes dumb people."

How did The Hills beauty adapt to playing a cartoon genius?

"I hired an acting coach for the day," Lauren Conrad said.

"A lot of the lines later in the episode are very complicated. I'm talking a lot about history and theorems and conductors, and there are a lot of facts and a lot of huge words, and I had to say it as if it was coming to me very easily."

"I actually had to research some of them because the acting coach told me if I really understood what I was talking about, it would come through a little better."
