Aussie pop icon Kylie Minogue celebrated her 39th birthday in style this week, opting for a low-key celebration at home in London with friends and family, including sister Dannii. Some of the singer's more ardent fans were, however, not going to let the date slip by unnoticed, and left gifts, flowers and cards upon Minogue's doorstep. "We thought she'd feel a bit down because it was her first birthday since splitting up with Olivier Martinez," one fan told reporters. Minogue is currently working with DJ/producer Calvin Harris on the follow-up to 2003 LP Body Language.
