Lady GaGa Flashes Her Butt !

One thing is for sure.... the lady is totally newsworthy! Weather its her antics or her dresses, Lady GaGa is always in the news.

Rear View

'Poker Face' singer Lady Gaga exposed her rear end for the crowd to see when she took to the stage with Yoko Ono's We Are Plastic Ono Band.

Another crazy dress

Gaga, 24, was dressed in an outrageous bedazzled one-piece jumpsuit, which had only sheer panels of fabric and a smattering of crystals covering her rear end.

Yoko Ono dwarfed!

The singer towered over Ono, 77, as she sported a pair of lace-up black boots with sky-high heels and a black headband embezzled with spikes.

GaGa tweets

'We Are Plastic Ono. I got to sit in as a guest musician tonight, what a legendary band mother, Yoko,' Gaga tweeted to her fans.

In honour of John Lennon

The concert at the Orpheum Theatre in Los Angeles kicked off what will be a week of events in honour of Ono's legendary late husband, John Lennon, whose birthday is October 9.
