Britney Thinks The "World is Cruel"

Her costly Mexican sombrero went well with her cat suit, Zorro Mask, Wizard of Oz shoes, and Elton John glasses.

Her body looked fit and sculpted!

Brit's shoes matched her outfit really well

Britney went ALL OUT on her costume for a house party thrown by model Heidi Klum and husband Seal, and later hit the Green Door bar with her friend Lucy Walsh. She really used her imagination, spending a total of $17.00!

Before Britney began her Halloween celebrations, she gave her first interview amid the media frenzy over her child custody hearings.

She told a radio station that the world can be "cruel" but insists she's doing the best she can when it comes to raising her two sons. LIKE. SHE. IS!

Spears told Ryan Seacrest: "You just try to keep doing what you do and as long as you know what's up and you know what's true, that's all that really matters - you know."

Seacrest asked Spears, 25, if criticism of her parenting skills bothered her, and she lamented on how "sad, you know, how people ... how cruel our world can be.

"But at the end of the day, like I said, you know, you just got to know in your heart that, you know, you're doing the best that you can and, you know, that's basically it," Spears said. Wow. she's really.... STUPID.

The ruling followed a hearing last Friday at which a parenting coach testified that Spears "rarely engaged with the children in conversation or play" and the boys had no real schedule or routine, according to court documents.

Seacrest asked Spears if she was doing everything she could for her kids, and the singer replied, "Oh God, yes".
