Lady GaGa broke down on stage last night (27.05.10) during an emotional tribute to her sick grandfather.

The 'Paparazzi' singer - who was performing the first show of her second UK 'Monster Ball Tour' in Nottingham, England - dedicated her performance of 'Brown Eyes' to her ill relative and had to wipe tears from her eyes during the song.

She told the audience: "If we all sing loud enough, maybe he can hear us!"

Although she was clearly upset, the flamboyant pop star continued her dramatic concert which has an enormous stage production.

The 24-year-old singer has previously described her stage show as "ostentatious and over-the-top".

She said: "For the next version of the 'Monster Ball', I'm throwing out the stage. My team thinks I'm completely psychotic. But I don't f***ing care what they think.

"Just to give you an idea, the stage is about four times the size of the first one and conceptually, it's completely different. One thing that has been lost over the past 10-15 years, in pop music, is the idea of showbiz. And this is definitely bringing it back."
