After reading so much about the use of celebrities in advertisements, I've found myself paying much more attention to commercials using celebs. T-mobile's decision to use Catherine Zeta Jones is one that doesn't make much sense to me. It's not that she has a negative image, but she's also someone I'd bet knows little about technology or cell phones.
One factor that crucial to analyze is whether or not the celebrity is credible for a given product or category. Sean "P. Diddy" Combs is a credible celeb for Ciroc vodka. Known for throwing some of the largest celebrity parties and his overall lifestyle, I'd trust him to know a thing or two about quality alcohol. Then there is Angelina Jolie for Louis Vuitton. I consider Angelina Jolie to be a style icon, so she is a quite credible source for the LV brand, and I'd trust that she'd actually wear their clothing.

In highly image-driven consumer categories such as fashion, perfume or liquor, celebrity endorsements can be credible. For sporting goods, endorsement by an athlete can work wonders. Look at Michael Jordan's success with Nike. However, categories that require more consideration, such as financial services or technology, a celebrity endorser isn’t likely to have much of a positive impact. This might be why T-mobile decided to drop Catherine Zeta Jones when her contract ended. It can also explain the decision of Carl's Jr. to drop Paris Hilton from their ad campaign. It can be assumed that neither of these women are credible sources for either of these products, leaving me to have a hard time taking these ads (or brands) seriously.
