Madonna breaks down ahead of Super Bowl gig

Madonna was reduced to tears after admitting she is exhausted from her Super Bowl rehearsals.

The singer, who will perform her new single 'Gimme All Your Luvin'' at this year's halftime show, broke down at the New York premiere of her latest film W.E as she discussed her ambitious plans for the gig.

"I'm sorry if I cry. I'm just so exhausted from Super Bowl rehearsals," Metro reports her as saying.

Madonna previously told ABC News of the set: "I have eight minutes to set up my stage, 12 minutes to put on the greatest show on Earth and seven minutes to take it down so the football field is clean for the second half. That's the challenge. How do you do that? I wanted to have 100 drummers come from the ceiling."

Asked if the song's guest features MIA and Nicki Minaj will join her on stage, she teased: "I am not saying 'Yes' and I am not saying 'No'."

will.i.am recently revealed that Madonna will duet with LMFAO for the performance, while it has also been speculated that Cee Lo Green will join her on stage.
