EXCLUSIVE PHOTOS - Britney Spears Goes Halloween Costume Shopping With Fiance Jason Trawick

Britney Spears and fiance Jason Trawick went Halloween costume shopping in Calabasas on Saturday, and while the pop star is still blonde and going bra-less, she looked a bit er, worn out. Maybe her X Factor judging gig isn't as easy as she thought it would be? After all, she did break down in tears the other day. And what's with her not wearing her engagement ring? So many questions!

In other Brit Brit news, a decision is due by Wednesday regarding Sam Lutfi's lawsuit against her family for breach of contract and defamation. Lutfi is going after Britney's mother Lynne Spears over allegations she made against him in her book, Through The Storm. Lutfi tried to have Britney deposed last year, but the judge wouldn't allow it because she was (and still is) under conservatorship. If the parties involved aren't able to settle by Wednesday, the judge will set a date for a hearing and the suit will move forward.

While Britney may be dealing with a lot of stress these days, she does have one thing to look forward too, as someone has given her the go ahead to start driving again. It may be a SmartCar, but she doesn't seem to mind ... just look at the smile on her face!
