Britney Spears and her husband Kevin Federline are now upping the ante in sun protection: there is now a SECOND SPF in the family, Sutton Pierce Federline, born September 12 and little brother to the first SPF, Sean Preston Federline. And it seems like everything in the Spears-Fed household happens in the same week in September: today is Brit and KFed's second anniversary, SPF1 was born September 14, and SPF2 born September 12...maybe they just like to have sex in December?
