Hottie of the year Miley Cyrus seems to be happy after finishing the rehearsal for her upcoming performance in front of the Queen of England. On Sunday night, December 6, the Disney sensation was seen smiling for the waiting paparazzi outside the Hilton hotel in Blackpool. That night, she sported a more mature look since she was spotted donning a leopard-print dress. The “Hannah Montana” star is due to perform at 2009 Royal Variety Performance which will be held at the Blackpool’s Opera House on Monday, December 7. She will join previously-announced performers, including Bette Midler, Michael Buble, Alexandra Burke, and Mika. As of the press time, it is still unclear what song the 17-year-old actress/singer will deliver on the show.

Royal Variety Performance is an annual show which is held in aid of the Entertainment Artistes’ Benevolent Fund, whose patron is the Queen. This year, the show feature a performance by “Britain’s Got Talent” winner Diversity, who considered the gig as part of their prize for winning the talent show. Set to close the event is electronica artist Lady GaGa.
