Britney Spears back on Instagram after engagement celebration and shocking account deactivation

Britney Spears is back on Instagram.

Days after shocking fans by suddenly deactivating her account, the pop star, 39, returned to the social media platform Monday, with a new post about her engagement celebration.

"Some shots from my weekend getaway to celebrate my engagement with my ... holy (expletive) ... FIANCÉ ... I still can’t believe it !!!!" she wrote, captioning two pictures of herself. "I couldn’t stay away from the gram too long so I’m back already !!!!"

Spears also commented on her new hairstyle in the photos. The singer recently cut her hair short and dyed part of it red, but in the new images, she's seen with her usual long blonde locks.

"Psss I took these in Palm Springs with clip in extensions," she added.

USA TODAY has reached out to Spears' reps for further comment and details.

The singer's conservatorship battle has sparked worldwide interest and concern over the pop star's wellbeing, which made it all the more shocking to fans when the pop icon deleted her Instagram page on Sept. 14, suddenly cutting off her biggest platform to communicate with the public. 

"Don't worry folks ... just taking a little break from social media to celebrate my engagement," she tweeted the same day, adding her signature barrage of exclamation points and emojis. Though Spears has more followers on Twitter (55.5 million) than Instagram (34 million), it's a social media platform she rarely utilizes. 

"I'll be back soon," she promised. 

Taking down Spears' Instagram was her decision, her lawyer Mathew Rosengart told Fox News and Page Six.

As her conservatorship battle raged on, Instagram was where fans felt they could hear Spears authentically voice her feelings despite not having total control over her life. When those supporting the #FreeBritney campaign were concerned she was being held back from participating in the legal battle over who controlled her estate, Instagram became the outlet for Spears to update the public on her thoughts. With that outlet gone, though apparently temporarily, some fans applauded her step back into privacy, while others showed concern that her primary form of communication with the outside world was removed. 

For months, Spears has shared posts that ranged from lighthearted (see: her twirling dance videos) to candid and blunt (such as when she said in March that she was "embarrassed" by how she was portrayed in recent documentaries about her career and conservatorship).

One of her most recent post expressed gratitude for the #FreeBritney movement as her father and co-conservator Jamie Spears reversed his stance and filed documents to end her conservatorship. 

"Growing up in a world where basically almost everything I did was controlled by someone else... I hope this message gets to people who have been confused or manipulated by a system," Spears wrote. "No... you're not alone and no... you're not crazy !!!! People need to hear this before it's TOO LATE !!!! I've waited 13 yearsand counting for my freedom !!!!"

The Instagram news came just two days after Spears revealed her engagement on Instagram to her boyfriend of four years, Sam Asghari. 

"I can't (expletive) believe it," Spears captioned videos showing off the four-carat ring with shocked expressions. Spears added six engagement ring emojis and six exclamation points to her announcement.

"Look at that, do you like it?" Asghari asked of the ring in the short video, to which Spears replies, "Yesss!"

Hours after her social media break made waves, Spears was named one of Time 100's most influential people on Wednesday. Paris Hilton wrote a tribute to the "fighter" and "sweetest soul" who "grew up in the tabloid culture of the 2000s, when the paparazzi machine was accepted, unforgiving and cruel."

She added: "In 2021, the battle cries of #FreeBritney roared louder than ever from her global network of devoted fans and a concerned public. Our hearts broke when Britney spoke about her pain.

"Despite the darkness that has surrounded her life, Britney embodies joy and shares the light of her beautiful heart, forever the superstar," Hilton concluded. "So we stand by her and root for her as she turns pain into purpose, her unwavering spirit stronger than ever."
