Erin Lee Carr, the director of the 2021 documentary Britney vs Spears, which helped the #FreeBritney movement to gain momentum and Britney Spears' freedom from her conservatorship, is defending the pop star following her arrest. As we have been reporting, the 44-year-old singer was arrested for driving under the influence in Los Angeles last week after she was caught swerving and speeding. Cops allegedly found an "unknown substance" in her car, which sources say is Adderall. It's currently being tested to see if it has been mixed with other substances, like fentanyl, cocaine, or meth.
