Lauren Conrad was spotted outside the Ed Sullivan Theater in New York Tuesday, where The Hills star and budding designer chatted up David Letterman.

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.
