Britney Spears Wears #FreeBritney Shirt Ahead of Conservatorship Hearing

Britney Spears is not playing her cards close to the vest ... in fact, she's wearing them on her t-shirt -- she wants out of her conservatorship, and it could happen today.

Britney and her fiance, Sam Asghari, mugs for the cam with the words, "#FreeBritney, It's a human rights movement" front and center.

It's no secret Britney wants the 13+-year conservatorship to come to an end at Friday's court hearing. That could happen, but it's by no means certain.

Terminating the conservatorship is squarely before the judge. Her attorney, Mathew Rosengart, has presented his case ... that it's incongruous for someone to be under a conservatorship who is also able to work and function day-to-day. He's also alleged a slew of misdeeds on the part of conservators and others, including Britney's dad, Jamie Spears.

The key to the hearing will be whether the judge orders a mental evaluation ... something that has been regularly done and evaluated every year of the conservatorship. Britney has made it clear, she does NOT want such an evaluation, and even Jamie Spears has done a 180 and said his daughter's conservatorship should end without such an evaluation.

The judge could still order a mental evaluation, but she's given no indication which way she's leaning.

One thing is clear ... Judge Penny is sympathetic to Britney. After the singer unloaded in court last June -- laying out in detail how the conservatorship has been torturous for her -- the judge complimented her bravery in speaking out.

The hearing is set for 1:30 PM and TMZ will be all over it.
