Jennifer Lawrence in Jeans at LAX | Pictures

Jennifer Lawrence was casual when she walked through LAX yesterday. She's heading out of town after a stay on the West Coast that afforded plenty of time to exercise at her gym, shop, and take meetings. The Fall is shaping up to be quite busy for Jennifer, who's due to start shooting the Hunger Games sequel, Catching Fire — see which other actors have nabbed roles in Catching Fire! She also has House at the End of the Street out in September, followed by Silver Linings Playbook in November. Jennifer also just had a birthday. She turned 22 last Wednesday — and we marked Jennifer Lawrence's birthday by checking out the leading lady's 22 boldest pictures.
