Hayden Panettiere walked the red carpet at ABC's upfronts presentation, but rather than Nashville spoilers, the actress' shiny new finger jewelry had everyone talking wedding plans.

Panettiere wore the ring on her right hand, but it's notable that in the Orthodox Christian faith, wedding rings are to be worn on the right hand: it is "symbolically the hand of power and that of the highest status," according to website OrthodoxAnswers.org.

She had rented a condo for the duration of the show's first season -- her neighbors included country star Taylor Swift -- but let her lease expire while ABC considered whether to renew the show. Since then, she said she's been living on friends' couches.

But with the renewal, Panettiere is free to house-hunt again, and she thinks it may be for good. "Even if the show didn't go on," the actress recently told New York Magazine, "I would always want to have some sort of a base here.
