Britney Spears is very pregnant. The former pop star reportedly stated that she felt like she'd been pregnant for "ten" years and she literally has been with child for most of the last two. Star Magazine says Britney is ready to give birth quickly. As in - next week. Star is reporting that Brit's due date is September 14. The reason - according to Lloyd Grove - is so papa K-Fed can keep track of the dates. Baby Sean Preston was also born on Sept. 14 and the C-Section for the new baby is scheduled, reports the NY Daily News columnist. The baby will be given the name Jailynn, which is a mash-up of the names of Britney's dad (Jamie), mom (Lynn), and little sister (Jamie Lynn).
