Miley has added an extra date at London’s 23,000-capacity O2 Arena to meet demand after selling out her 2009 U.K./Ireland tour.

The new date takes place on Dec. 29 and will form the fifth and final London show of her tour. All four existing London dates (Dec. 13, 14, 19, 20) have sold out, as have the artist’s shows at Dublin’s O2 Arena (Dec. 16 to Dec. 17), Birmingham’s LG Arena (Dec. 22 to Dec. 23) and Manchester’s MEN Arena (Dec. 27 to Dec. 28).

Tickets to the added London date go on sale Oct. 30 at 9.00 AM GMT, via www.ticketmaster.co.uk.
