Post-surgery, Gaga set for comeback

Singer Lady Gaga is reportedly ready to hit the stage with her first performance after her hip surgery which took place in February.

Gaga has chosen the popular ancient Roundhouse Hall, in London, which was once a railway engine shed, to launch her latest album "Artpop" in September, reports thesun.co.uk.

The gig is being hosted by iTunes and Gaga's team is spending 500,000 pounds on the production to make the show at the 3,300-capacity hall extra special. The hall is managed by Camden London Borough Council authority.

"The gig in Camden has a huge budget and is likely to be the first anyone sees or hears of her album. The Haus Of Gaga team have been working in secret on costumes and stage sets for the show from their base in Paris," a source said.

"Gaga's dancers have also been rehearsing but she's only told her closest friends about the new direction she's taking. The music is going to be a big departure and Gaga's dreamed up a whole new image for the album," the source added.

Celebrities like Justin Timberlake and Elton John have already been booked for the festival, which brings 30 nights of free music to the venue throughout September.
