Britney Spears took off for Louisiana earlier this morning to spend some time with her pregnant sister Jamie Lynn. Surprisingly, unlike many of her celebrity peers, the pop princess actually chose to fly Delta - way to be environmentally conscious, Brit!

With a little over a month to go before her due date, Jamie Lynn must be frazzled beyond belief - who wouldn't love a visit from their big sis in that situation? Besides, Britney's working on some big plans of her own - a trip home sounds like just what the doctor ordered!
