Lauren Conrad Bumps Bloomingdale's

Lauren Conrad signs autographs and poses with her fans at a Bloomingdale’s store in Los Angeles on Thursday.

The Hills star attended a signing session where a couple of hundred mostly teenage girls turned up to have their photograph taken with her, and have her sign magazines with her image on them.

Lauren, 22, recently gave $10,000 and her Teen Choice Award surfboard to a 13-year-old leukemia patient. Pat Pedraja, who lost a shot at a $100,000 grand prize in this year’s Do Something Contest, was given $10,000 and an iPod, courtesy of Conrad.
