Britney was spotted at one of her favourite gyms in Marina del Ray last night.  She was seen working up a sweat on the treadmill and having a conversation with her personal trainer, laughing in between all the hard work!

Later, Britney headed over to the recording studio in Burbank for another recording session.  Larry Rudolph wasn’t joking when he said she would be spending the summer in the studio!  Her mother also accompanied her.
