The 25-year-old star has not performed a full-length concert since *suffering vocal problems in 2011.
Now she is considering returning to the stage for the release of her third album, due out in October, and sources say she sees London’s Royal Albert Hall as the perfect venue.
The hush-hush show would be one of the hottest tickets in the capital as Oscar-winner Adele is one of the bestselling *artists of all time.
Executives at her record label hope she may follow this with concerts in New York and Los Angeles.
“This is the most exciting and promising news fans have had from Adele for ages,” said a source close to the star. “She is considering a comeback gig to promote her new CD.
“Her voice has been getting stronger over time and she has been working hard to rehabilitate it. A world tour is still a long way off, certainly a conventional series of shows.
“Everything will be on her terms. The key to all these plans is that Adele feels comfortable with her voice. She has vowed that she never wants to break down during a tour or put her voice through so much stress that she suffers problems. Her doctors warned her that stress could also mean more surgery, and she is adamant that she never wants to go through that again.”
The source, based in Los Angeles, said: “The delicacies of the situation are apparent to everyone from Adele to her management. She is very settled with her family life and being a mum. A lengthy trip around the world with a baby on board could change that.”
Mariah BETTER release in May, she seriously can't afford to push it back any further. I can't have her competing with the new vocal queen. but seriously, I'm SO excited for this!
