In the August issue of Teen People, Katharine McPhee reveals that she recently auditioned for the HBO hit Entourage.  The young female character would have a fling with actor Vincent Chase (a.k.a. ‘Aquaman’).  No word yet whether Katharine has landed the role—but I’m actually hoping she doesn’t get it.  Although the show thrives on actors playing true-to-life cameos, I think that bringing on any contestant from American Idol would cheapen the show—whether they are playing themselves or not.  The producers of Entourage should leave the bit parts for the real actors.
