Video of Lauren Conrad on Late Night With Jimmy Fallon

Lauren Conrad Is Sore From All That Smiling

Lauren Conrad mixed up another day of TV appearances with a book signing at Barnes & Noble in NYC yesterday. Most of you supported her decision to discuss Spencer's fake apology on The View, but her interview with Jimmy Fallon was a little more relaxed. Lauren admitted that she loves meeting her fans on her book tour but that she's hurting from keeping a permanent smile on her face. Jimmy also tested her acting abilities, but for now Lauren will be saving her skills for her life off camera.
