Start booking your flights into Heathrow, y'all! Rihanna has just signed up to headline the 2011 Capital FM Jingle Ball in London on Sat. Dec. 3 and Sun. Dec. 4, joining the ranks of fellow superstars like her 'We Found Love' collaborator Calvin Harris and Jason DeRulo, as well as English acts Pixie Lott, The Wanted, and Olly Murs.

Rihanna's currently stationed in London in the midst of a mind-numbing 10 consecutive shows at London's massive O2 Arena as part of her tour, so her performance at star-studded Jingle Ball will mark her 11 (!) performance at the venue this year. Let's hope that RiRi won't be tiring of Londontown anytime soon!

The Bajan banger actually headlined the first annual Jingle Ball back in 2008, though since then, fellow A-listers like Lady Gaga, the Black Eyed Peas, and Janet Jackson have been the main act at the event. We're hoping that Rihanna will seize the opportunity to play some new tracks from 'Talk That Talk,' which is due out Nov. 18. And hopefully by then, she'll be fully recovered from whatever bug or sickness she is currently dealing with!

Tickets for the event are on sale now!
