Bassey's spokesman, Paul Carey, said the 71-year-old had emergency surgery on her stomach after being admitted to a Monaco hospital last week with complaints of abdominal pains, the BBC said Saturday.

Carey said everything appeared to go well with the surgery and Bassey is "resting up and on the road to a full recovery."

The "Big Spender" singer, who offered her vocal talents to the theme songs for three "James Bond" films, is expected to perform at a June 27 concert in London's Hyde Park.

That event will honor the 90th birthday of noted anti-apartheid activist Nelson Mandela, the BBC said.
