Seems that being a Golden Globe-nominated actress, Michael Douglas’ better half, and the face of Elizabeth Arden isn’t enough. In June Catherine Zeta-Jones, 32, also became the global spokeswoman for wireless service titan T-Mobile International. As part of the two-year deal, the star of the upcoming Chicago will rep VoiceStream Wireless (now T-Mobile) in a campaign that includes TV spots directed by The Cell’s Tarsem Singh. Zeta-Jones replaces four-year VoiceStream vet Jamie Lee Curtis, 43. The Welsh native ”totally connected with our vision, which is a cross between the fun ‘girl next door’ and a magical catalyst for spontaneous communication,” says Bob Moore of ad agency Publicis in the West, Seattle. Uh, okay…but why would the glam actress want to hawk cell phones? A rep had no comment, but in a statement, the self-proclaimed technophile noted: ”I’m thrilled to be helping spread the message that people can live more and get more from their daily lives by using T-Mobile’s service, just as I do.” And we’re guessing the free service doesn’t hurt either.
