Pop princess Kylie Minogue will celebrate her 40th birthday on Wednesday.

Minogue who is currently on her X tour will perform a concert in Germany later.

She is scheduled to celebrate her 40th birthday with a small group of family and friends.

Her sister Dannii Minogue will be joining at what is expected to be a lavish sit-down dinner in Germany, while mother Carol and father Ron are flying in from Australia.

Minogue's tour resumes with a gig in Munich on Thursday, before moving to Switzerland, France and Spain.

Last week she kicked off her birthday celebrations in Greece.

Minogue booked a three-storey hotel overlooking the Aegean sea for her entourage.

More than 100 people celebrated at an all-night party, attended by people from her record label, her tour and management.

Her catering staff from the X tour were also invited - with Minogue hiring outside caterers so they could get the night off.
