Britney Spears is celebrating the birth of her second son today (12SEP06), according to US reports. Despite reports the pop superstar and husband Kevin Federline were expecting a little girl, the National Enquirer claims the TOXIC singer gave birth to a 6 pound 11 ounce baby boy just before 2am this morning at a Los Angeles hospital. An insider tells the tabloid, "Kevin took Britney to the hospital in the evening hours of September 11 to prepare for the Cesarean birth." The new addition to the Spears/Federline family was born two days before big brother Sean Preston's first birthday (14SEP06). Federline attempted to dupe the press in recent interviews, insisting his wife would give birth around Halloween (31OCT06).
