As Katharine McPhee came oh-so-close to winning American Idol this past season, a star from a different FOX show was cheering her on throughout the competition.
Rachel Bilson, who portrays the adorable Summer Roberts on The OC, says she following her former high school classmate very closely ... and tried to help her achieve victory.
"I went to support her and watched a taping of the show. I voted 100 times," Bilson said.
Alas, it wasn't enough, as Taylor Hicks walked away with the singing crown. But Bilson still has fond memories of performing with McPhee back in the day.
"We did a musical together. She was a freshman, I think, when I was a senior, so she's a few years younger, but we were friendly."
Bilson says she likes to sing "alone," so don't count on her trying out for American Idol 6. But will McPhee ever appear on The OC? You never know.
