Britney Spears' dreams of becoming a mother have finally been realised - the pop superstar gave birth to a baby boy yesterday afternoon (14SEP05).

According to American magazine Us Weekly, the 23-year-old TOXIC singer welcomed her first offspring into the world shortly before 1pm on Wednesday at California's Santa Monica UCLA Medical Center.

Spears and her dancer husband Kevin Federline, 27, arrived at the hospital with a police escort shortly before 6 am and medical staff whisked the star into a birthing suite, reports the publication.

According to hospital sources, Spears, who reportedly started experiencing early labour contractions on Friday (09SEP05), was wheeled into a delivery room at about 12.15 pm and within minutes she had delivered via Caesarian section with Federline by her side.

While the newlyweds - who will celebrate their first-year wedding anniversary on Sunday (18SEP05) - have yet to announce the name of their offspring, sources say they had planned to call the child PRESTON MICHAEL SPEARS FEDERLINE.

The child is Federline's third - he's also the father of daughter KORI, three, and son KALEB, one, with ex-girlfriend Shar Jackson.

In a recent interview with Elle magazine, Spears made very specific predictions about the arrival of her child, saying, "I have a feeling I'm going to have an operation. I don't know why. But I hope so. I don't want to go through the pain...

"I don't know the sex. I want to be surprised. But I have a feeling that it's going to be a boy. I've always wanted a boy and then two girls."
