There was a time when circumnavigating the globe in 80 days was considered quite an achievement, but pop diva Christina Aguilera has managed the feat in just 60 seconds in a new advertising clip.

America's favourite songstress samples the delights of a series of exotic cultures in Pepsi's latest publicity drive. The Dirrty singer finds herself a Bedouin in the desert, dancing the samba in Rio de Janeiro, hitting a high note in snowy Prague and shaking her booty in a Japanese geisha bar, before she is transported back to the relative normality of a New York recording studio. "I had a great time," said the chanteuse after filming the ad. "It was fun to dress up and to be myself."

The chart-topper used to promote arch-rivals Coca Cola, but last year she switched sides to Pepsi in a deal believed to be worth 2 million. She is just the latest in a series of high-profile singers to represent the soft drinks firm, as Britney Spears, Beyonce Knowles, Pink and Jennifer Lopez have all appeared in previous campaigns.
