16th January - She's turning 21 in April this year, loves Snickers bars and was in Singapore recently for an exhibition match with Anna Chakvetadze. She's none other than Russian tennis star, Maria Sharapova.

The highly profiled player today pledged her allegiance to Sony Ericsson. Besides undertaking a series of new consumer-brand campaigns off the court, Sharapova will also be working with the Japanese-Swedish company's designers on "a range of products and accessories," according to the press release.

Guess what phone she's using now? The Sony Ericsson W350i. What did you expect?

Correction: We were just alerted to the press release dated 8 January that Canon USA has extended its global marketing relationship with Maria Sharapova until 2010. Changes have been made to the original article.
