Wow. Is this lame or genius? Hard to tell.
The Internet serial "Lonelygirl15" will get star treatment Friday when "American Idol" runner-up Katharine McPhee plays a guest role.
McPhee was an early fan of the show, which unravels the mystery of a 16-year-old girl named Bree in short video segments posted on YouTube, Revver and an official Web site.
"I followed it from the beginning," McPhee told The Associated Press. "I thought it would be fun to meet all those characters."
McPhee's management contacted the creators of the Web series about a guest spot. The writers had already been devising a female character who briefly meets Bree and had been searching for ways to cast fans as characters. They readily agreed to cast McPhee in the nonrecurring role.
"She has an album coming out and thought it would be fun to go on the show," said "Lonelygirl15" co-creator Miles Beckett.
