David Bowie's representative has thanked fans for giving the star a birthday to remember by sending his new song to the top of the charts.

The reclusive musician returned to the spotlight on Tuesday (08Jan13), the day of his 66th birthday, by releasing his first new music in a decade.

The new track, titled Where Are We Now?, shot straight to the top of Britain's iTunes chart, and a spokesperson for Bowie has now reached out to fans and thanked them for their support.

A message posted on Bowie's newly-revamped website reads, "The response... has been incredible and what nicer way to wish David Bowie a Happy Birthday than with all the positive responses on Tv, radio, newspaper and social media sites.

"The reaction from iTunes users has also been remarkable with... the single, Where Are We Now?, currently at #1 on the Uk iTunes site."

Bowie's new album, titled The Next Day, is due to hit stores in March (13).
