britney playing tennis in rehab

Britney Spears is at last seen having fun in rehab! She was spotted exercising & playing tennis with a friend on a court on the premises of Promises center.
She seems happy & has that old look back on her face; the one of the fun & joyful Brit Brit.
The good thing is that Britney looked comfortable.
I hope this means that she'll really be back to her old self after the rehab program ends.
