So much for getting Amber Heard. Just in time to be paraded before the Comic-Con fanboys, 22-year-old Laura Vandervoort, whom fans of The N (our Angel Cohn included) know as Instant Star's Sadie, has been cast in the role of Smallville's Kara, aka Supergirl. This superstrong - and airborne! - newcomer may prove to be a super- pain to her kin, however. "We've wanted a character to shake things up," series creator Al Gough tells People. "She may be Clark Kent's cousin, but that doesn't mean she's going to be the obedient one!" Sounds like Paris Hilton, minus the gravitational pull. Actually....

For the complete story on how Smallville will introduce its take on Supergirl, see the TV Guide News Report.
