Now that the McCain/Palin ticket has usurped Barack Obama to become the official celebrity story of the day, actual celebrities are weighing in on Palin, and the reception is mixed. Following in the footsteps of Palin critics Lindsay Lohan and Albert Brooks, here's the latest roundup of stars going political: · Heart's Nancy Wilson has taken umbrage at the use of their band's song "Barracuda" to introduce Palin at the RNC (Palin earned the nickname "Barracuda" during her high school basketball days). "I think it's completely unfair to be so misrepresented," she said to EW. "I feel completely fucked over." · Diddy has much warmer feelings toward the vice presidential candidate, though they're expressed in equally blue terms. "You did your thing," he said on his Diddy Blog after watching Palin's RNC speech. "You gave a speech that pretty much shut me the fuck up."
