Britney Spears Celebrates 'Best Day Ever' After 13-Year Conservatorship Ends; Lady Gaga Reacts

Britney Spears was finally freed from her longstanding conservatorship Friday, and both fans and celebrities are celebrating alongside the pop superstar.

Spears, 39, took to Instagram to post a video of #FreeBritney supporters celebrating the end of the singer's 13-year conservatorship in the street outside the courthouse. In the clip, fans cheer while holding pink flags and signs with the words "Free Britney," with confetti falling from above.

"Good God I love my fans so much it’s crazy," Spears wrote in the caption. "I think I’m gonna cry the rest of the day!!!! Best day ever … praise the Lord … can I get an Amen???? #FreedBritney."

Newlywed Paris Hilton, one of Spears' friends who openly supported her during her conservatorship battle, commented, "Yasssss," with a face with party horn and party hat emoji and heart eyes emoji.

"We [red heart emoji] you, Britney!" Andy Cohen wrote.

"Oops, you did it again!!!! Amen!!!!!!!!" Keita Moore commented.

"I am overjoyed for you. You deserve every good thing," Wil Wheaton wrote.

"And the church said AMEN!!!!! FLY," "Selling Sunset" star Chrishell Stause added.

Lady Gaga also posted on Instagram a sweet tribute for Spears, sharing a throwback photo of herself in drag as her alter ego Jo Calderone kissing the "Toxic" singer at the 2011 MTV Video Music Awards.

Gaga accompanied the snap with a touching caption reflecting how Spears touched her life.

"I have loved @britneyspears her whole career," Gaga wrote in the caption. "I looked up to her, admired her strength—she empowered so many people and still does. I couldn't be more happy for you today. You never deserved what happened. Thank God for today. You’re a superstar and a super-human being. I LOVE YOU."

Spears' conservatorship was terminated Friday when Los Angeles County judge Brenda Penny approved her dad Jamie Spears' petition to end the legal arrangement.

The pop star's attorney Mathew Rosengart called it a "monumental day" after the ruling. "What's next for Britney is up to one person — and this is the first time we can say this in a decade. It's up to Britney," he said. "Britney, as of today, is a free woman."

Earlier this month, Jamie's lawyer, Alex Weingarten, wrote that the Spears patriarch believed "Britney's recent testimony and requests to take personal control of her estate and affairs have made clear that continuing the Conservatorship is contrary to her desires."

The court document added, "Jamie sees no reason why the Conservatorship should continue for any amount of time and asserts he has no interest in the Conservatorship continuing."

Jamie said his request was "unconditional" and that there were no demands for release or compensation because he "unconditionally loves and supports his daughter," according to the lawyer.
