Britney Spears is back with her is the last U.S. leg of her Circus Tour, and the final show is in Las Vegas at The Mandalay Bay Events Center. The Circus tour started in the states and then headed over to foreign land, but she's back and says the Circus tour has been revamped to include different songs and more cities on its second U.S. run. The Circus tour includes songs from Britney’s past albums and her comeback jams off of Circus, so you can hit her baby one more time and jump in the center of the ring for two whip-crackin,' tiger-tamin' shows in Las Vegas.
