Britney Spears Calls Out Mother and Sister for 'Self Righteous' Social Media Posts

Hell hath no fury like Britney Spears scorned.

The Princess of Pop took to her Instagram account Friday evening and made it very clear that family members who are now showing public support to end her conservatorship and posting messages online can shove those "self righteous" thoughts right where the sun don't shine.

Britney did not drop her mother and sister's name specifically, but the timing for her social media shade comes the day after both Lynne and Jamie Lynn Spearsdropped their own cryptic messages online about showing support to the embattled singer.

"The light shines in the darkness and the darkness has not overcome it," Lynne wrote on Instagram, while Britney's younger sister also wrote a few inspirational quotes: "Once you choose hope, anything's possible," and "Dear Lord, Can we end this bull sh#t once and for all. Amen."

Britney has now responded with a lengthy message of her own, and the sentiment is clear: STFU

"There’s nothing worse than when the people closest to you who never showed up for you post things in regard to your situation whatever it may be and speak righteously for support … there’s nothing worse than that !!!! How dare the people you love the most say anything at all … did they even put a hand out to even lift me up at the TIME !!!??" Britney captioned her message.

The singer added, "How dare you make it public that NOW you CARE … did you put your hand out when I was drowning ???? Again … NO … so if you’re reading this and you know who you are … and you actually have the nerve to say anything about my situation just to save face for yourself publicly !!!"

As we reported, Britney has publicly blamed her entire family for taking part in the conservatorship, which she recently described to a judge as a prison. Although Britney's mom recently tried to take a bigger role in the conservatorship, she had ignored her daughter's situation for years and let Jamie Spears take control of the entire situation. Britney's sister, Jamie Lynne, also once tried to assume control of the conservatorship ... a move that now seems to have not been in her sister's best interest.

Posting a final message to her "inner circle," Britney wrote:

"If you’re gonna post something …. Please stop with the righteous approach when you’re so far from righteous it’s not even funny …. 🖕🏼🖕🏼🖕🏼 and have a good day !!!!! PS if you’re reading this today and you can relate …. I’m sorry because I know what it’s like … and I send you my love."

Britney has vowed to sue her entire family, especially her father, over the treatment during her conservatorship.
