The 37-year-old singer shared a new Instagram video on Wednesday of her working out, set to Cardi B, Bad Bunny and J Balvin's "I Like It." Spears lifts weights in a bright yellow sports bra and black pants, also happily showing off a few dance moves.
"Who knew stress would be a great 5 pound weight loss. Yay for me," she wrote, adding winking emojis.
"Hi guys, just checking in with all of you who have been concerned about me," Spears said in the video. "All is well. My family has been going through a lot of stress and anxiety lately so I just needed time to deal. But don't worry I will be back very soon."
In a lengthy caption, Spears also said that the recent rumors about her were "out of control."
"There’s rumors, death threats to my family and my team, and just so many things crazy things being said," she wrote. "I am trying to take a moment for myself, but everything that’s happening is just making it harder for me. Don’t believe everything you read and hear."
"My situation is unique, but I promise I’m doing what’s best at this moment," she continued. "You may not know this about me, but I am strong, and stand up for what I want! Your love and dedication is amazing, but what I need right now is a little bit of privacy to deal with all the hard things that life is throwing my way. If you could do that, I would be forever grateful. Love you ❤️❤️❤️."
Earlier this month, a source told ET that Spears checked herself into a health facility to deal with the tremendous stress she's been having over her father, Jamie Spears', current health crisis. A few weeks earlier, she had put her career on an indefinite hiatus, postponing her album and putting her Britney: Domination show at Park Theater at the Park MGM resort in Las Vegas on hold in order to support her father.
Spears has been spotted out multiple times while still in treatment, most recently on Easter Sunday at the Montage hotel in Beverly Hills, California, where she was with her longtime boyfriend, Sam Asghari. A source tells ET that Spears remains in treatment but is allowed "outings," as she works on her "mind, body and soul."
