The pair talked about what Lauren Conrad was like as a child.
"Our house was in Orange County. The back was a huge canyon, and I was a really big tomboy when I was little," Lauren Conrad said. "I'd always go hiking and I had a rock collection. And I'd come back up and... you get ticks! They're gross!"
Yup, that pretty much sums it up.
Lauren Conrad also revealed that she is taking a computer class at the FIDM with none other than Stephanie Pratt! OMG! David Letterman also refers to the great Spencer Pratt as a newt (a reptile), which is pretty classic.
