Bollywood superstar Shah Rukh Khan has announced the arrival of his new baby boy born to a surrogate mother, and denied rumours of an illegal pre-natal gender test.In a statement released today, he said he and his wife Gauri had kept quiet on the matter owing to their "emotional strife" after the child, named AbRam, was born several months premature, reported The Straits Times."Just to put the record straight there was no sex determination for our child," said Khan, 47, adding that the baby was born before such suspicions arose in the media.Mumbai officials said last week they had received confirmation from a city hospital that a baby boy was born on May 27 to the Khans. Rumours surfaced in June that the Khans were expecting a boy, raising speculation they had carried out a sex test.Such a test is illegal in India, to try to prevent parents aborting female foetuses.On seeing the reports, the Indian Radiological and Imaging Association wrote to health officials demanding an investigation.Khan, 47, and wife Gauri, 42, already has two teenage children, a girl and a boy. He confirmed that his new child was born by surrogacy, an arrangement in which a woman carries the child of another couple."The entire process is bound by strict confidentiality. We would appeal to all, to allow us, to cherish this private moment as a family," he said.
