Confirmation is in for Britney Spears' first dates of her 2009 world tour. She will play the O2 Arena in London on June 3 and 4.

The shows will be Spears' first European dates in five years, but, more importantly, will kick off a world tour as she attempts to make a comeback from personal problems that have been well-documented in the tabloids and mainstream press.

Spears' camp has announced that there are no other European dates announced for 2009.

Tickets for the London shows go on sale December 5. Presale tickets will be made available through Spears' web site.

Spears tour, her first since a mental breakdown that led to a Sinead O'Connor-like hair cut, among other things, will back her latest album "Circus". Spears has signed a production contract with AEG for the Circus tour.
