Lady Gaga headed to a studio in London to film Friday Night With Jonathan Ross last night which she is scheduled to be appearing on tonight.

She is preparing to perform her first ever Russian gig in Moscow's Famous Club next week. On Sunday, her song Poker Face was knocked off the top spot after three weeks in the British singles chart by Calvin Harris 'I'm Not Alone.'
