BRITNEY WELCOMES 2ND BABY? © WireImageBritney Spears reportedly checked into hospital to deliver her second child by a secret Caesarean section yesterday (09.07.06). The "Baby One More Time" singer and husband Kevin Federline have allegedly scheduled an appointment at the UCLA Santa Monica Medical Center, in California, exactly one week before son Sean Preston's first birthday, according to website Dlisted. Kevin recently told reporters that Britney was due to give birth in October. It is common among the rich and famous to give birth by elective C-section approximately four weeks before the baby is due. The procedure is carried out for cosmetic reasons, as the stomach skin most commonly stretches the most in the last month, so having the baby delivered early limits the possibility of unsightly stretch marks. The couple have already chosen a name for their baby which is believed to be a girl. Britney is combining her mother and father's names, Jamie and Lynne to create Jailynn. It was reported last month the pop superstar had ordered nursery accessories off the internet, including a cot, which were pink and suitable for a girl.
