After the hellish night she endured, Britney spent the day indulging herself - and it seems to be having the desired effect!

Brit's first stop was the Mercedes dealership, where she and her mother signed a few papers.

From there, the pair met up with Sam at the Beverly Hills Hotel for lunch. After that, Brit and Sam headed over to the Century City Mall for a quick J. Crew run.

Fortunately, our photogs are reporting that Britney's mood seems greatly improved from last night - they all said she was very much enjoying her shopping expedition!

And as much fun as Britney may have been having at the mall, she had a great reason for getting home - she told X17 that she'll be having one of her telephone calls with her kids today!

We're also quite pleased to see Lynne and Sam getting along - after the reports of animosity between Britney's parents and Sam, we think it's great to see Lynne making an effort to get along with her daughter's friends!
