AnnaLynne McCord Being Cast In Twilight?

Word on the street has it that AnnaLynne McCord is another actress being considered for the part of one of the Volturi in Twilight, the role of Heidi, specifically.
She's dating Kellan Lutz, who plays Emmett in the film and is also on 90210, so I'm sure these two would love the chance to work together off the show as well! 

A source tells Internet blogger Marc Malkin, "It’s not a big part. Heidi would be more like a cameo." 

Twilight fans, what do you think: Yay or nay on AnnaLynne as Heidi?
