Madonna Goes Into "Meltdown" Mode During Gig

Madonna was sent into "meltdown" mode last night after her show was hit by technical faults.

The Material Girl singer -- who was in Nice, France, for the French leg of her Sticky & Sweet world tour -- was furious after the massive screens bought in for the multi-million dollar show went blank during several songs.

A source tells British publication the London Paper, "Madonna sets very high standards for herself and for those working around her, so when things go wrong she gets annoyed.

"With so many friends in the audience it was doubly annoying for her."

U2 frontman Bono was spotted in the crowd, carrying cigars in his top pocket while dancing with a group of friends. David and Victoria Beckham also flew into France especially for the show, while Elton John and husband David Furnish cheered enthusiastically from their VIP seats.

The Sticky & Sweet tour, which has been described as a "rock driven dancetastic journey", features four acts: Pimp; Old School; Gypsy; and Rave.
