Britney Spears is a casual traveler!

The 29-year-old singer was seen at LAX on Wednesday with her beau Jason Trawick, and Brit was looking cute and casual in a green t-shirt and black leggings.

Brit is one busy lady!

Not only is she gearing up for the European leg of her Femme Fatale tour, but she has a remix album coming out and both of her sons celebrated their birthdays this week!
