NEW YORK – Victoria Beckham seems to be getting used to filling a fourth judge chair on "American Idol," left vacant by Paula Abdul's departure.

Fox publicist Alex Gillespie says the former Spice Girl is in Boston for callbacks. Beckham was a guest judge last Friday for opening auditions in Denver, and it was originally described as a one-time appearance.

This is the point of the show where judges give singers a golden ticket to advance to the Hollywood round.

Last week in Denver, Beckham told Fox News she was a huge fan of "American Idol" and nervous about being a judge. "My heart is about to jump out my throat," she said.

"American Idol" returns for its ninth season in January.
