Lady GaGa unveiled a host of new costumes as she kicked off her first full US tour in San Diego last night (March 12th).

The singer wowed a sold-out crowd at the House of Blues with tracks from her debut album 'The Fame'.

Her setlist included new single 'Poker Face' and the worldwide smash hit 'Just Dance'.

Lady GaGa also ensured she lived up to her reputation for creative innovation, debuting an outfit made entirely of bubbles.

The bubble wrap costume appeared to make it hard for the singer to sit down when she tried to play a piano-led number mid-way through her set.

The Fame Ball Tour will call at venues across across the US and Canada throughout the spring.
