Virgin Mobile Canada is sponsoring the Britney Spears Circus Tour. To make things a bit sweeter they have created a dedicated site to keep up with the latest gossip, news, offers and videos from the tour. The first concert kicks off in Toronto March 18th. Check out the site here. For those who are with Virgin Mobile and going to the shows, you’ll be able to text Brit before the show and those will be entered into a draw for the ultimate opportunity to get a seat upgrade.
