Uinterview - u ask. they tell.

A young girl's life changed last week when ex-Tonight Show host Conan O'Brien decided to follow her on Twitter – the only person he's following.

"I've decided to follow someone at random. She likes peanut butter and gummy dinosaurs. Sarah Killen, your life is about to change," O'Brien tweeted.

O'Brien, who has apparently been bored to death during his hiatus from television, later posted, "Sarah likes Twizzlers and craves cantaloupe. I like Raisinets, but melon feels creepy in my mouth. Twitter pals 4 eva! :)."

Killen (@LovelyButton), 19, from Fowlerville, Missouri, spoke to AOL's PopEater.com about how O'Brien has helped her out. "It's changed my life," she said. "I'm getting married on September 25, and we didn't know if we would be able to afford [a dress]. Now I'm getting custom made shoes and dress from Kelima in New York." –JOE GALBO
