Indian film superstar Shah Rukh Khan has denied he knew the gender of his son before the boy's premature birth.
Prenatal gender testing is illegal in India to prevent sex-selective abortions.
Media reports cite the Bollywood star saying he did not comment on the rumours earlier because of "emotional strife" over the health of the baby.
His statement said "there was no sex determination for our child" and that the baby was born before the media speculation began.
Reports say the boy born via a surrogate is named AbRam Khan.
Khan and his wife also have a son and a daughter, who are in their teens.
The statement did not say how premature the baby was but thanked all the doctors and nurses who looked after him and "who have made his life possible".
"Our son is a surrogate baby and the entire process is bound by strict confidentiality. We would appeal to all, to allow us to cherish this private moment as a family," his statement added.
In 2011, actor Aamir Khan spoke openly about how he and his wife, film-maker Kiran Rao, had struggled with fertility issues before they decided to have a baby using a gestational surrogate.
India's 2011 census showed that the country had 914 girls for every 1,000 boys younger than six, a skewed ratio mainly attributed to abortions of female foetuses despite the ban on pre-natal gender tests.
