Britney Spears has been warming up for her US comeback performance with a trip to the circus in New York city.
The pop princess - who is scheduled to appear on Good Morning America today - is planning on blowing away audiences with real circus performers.
"It's going to be pretty wild," an eyewitness tells OK!
"Brit was dancing in the ring with her regular team, while stilt walkers towered over her and the gymnasts were throwing themselves all over the place."
Britney has just returned from receiving a luk warm response in Europe after appearing on the U.K.'s The X Factor, France's Star Academy and Germany's Bambi Awards.
Let's hope her last minute rehearsals pay off today...
