The pop star Britney Spears gave birth to a healthy baby boy on Wednesday, entertainment websites reported. The baby was delivered in a cesarean section shortly after 1:00 pm (2000 GMT) in Santa Monica at UCLA medical center, according to Us Weekly magazine's website.
Spears, 23, who rose to fame as a teenager, had said beforehand she was dreading the pain of childbirth and hinted she would opt for a cesarean, the website E!Online reported.
A spokeswoman for Spears contacted by the AFP declined to confirm the reports.
It was Spears' first child with husband Kevin Federline, 27, a former backup dancer, who wed the star a year ago. Federline has two other children from a previous relationship with actress Shar Jackson.
Since her marriage, Spears has broken with her manager and spoken about settling down to start a family in her lavish mansion on the California coast.
