The sizzling pics caught the attention of several stars, including fellow singer Tinashe. "BRITNEYYYYYYYYYYY," she wrote in the comments section. Paris Hilton also reacted with her famous catchphrase, "That's hot."
Spears is currently in the midst of her ongoing conservatorship battle. In mid-July, she scored a major legal victory when Los Angeles County Superior Court Judge Brenda Penny ruled that she can hire her own lawyer in her pursuit of ending the conservatorship that has controlled her life and career for the last 13 years. And for the first time, Britney used the viral hashtag-turned-movement "#FreeBritney" in celebration.
The singer has also made shocking claims in court, including that she's unable to remove her implanted birth control and have more children and that she was once put on lithium against her will.
In addition to speaking out in court, Spears has also been newly vocal on social media, with a couple of scathing posts last weekend that targeted those closest to her, including sister Jamie Lynn Spears and dad Jamie. "My so-called support system hurt me deeply !!!!" Britney said in one post.
