Britney Spears appears to criticize her sister and mother, calling out those closest to her 'who never showed up'

• Britney Spears criticized those closest to her for not supporting her amid her conservatorship battle.
• Fans speculated that the Instagram post was about her sister Jamie Lynn and mother Lynne.
• Spears has been publicly battling to end an "abusive" 13-year conservatorship.

Britney Spears has criticised the people closest to her for speaking about her publicly while not supporting her privately.

"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," Spears wrote on Instagram.

"How dare you make it public that NOW you CARE … did you put your hand out when I was drowning ???? Again … NO …," Spears wrote.

The singer has been publicly battling to end the "abusive" conservatorship she has been under for 13 years. The legal arrangement grants control of her personal life and estate to a group of people including her father, Jamie Spears.

While Britney Spears did not name anyone in the Instagram post, she said it was about the people she loved the most.

"You know who you are," she wrote. "Please stop with the righteous approach when you're so far from righteous it's not even funny."

Spears's Instagram post was flooded with comments speculating that it was targeted towards her younger sister, Jamie Lynn Spears and her mother, Lynne Spears.

Both had posted cryptic messages on Instagram following a judge ruling that Britney Spears could choose her own lawyer for her conservatorship case.

On Wednesday Lynne Spears posted an image on Instagram which read, "The light shines in the darkness, and the darkness has not overcome it."

Jamie Lynn Spears posted an Instagram story on Thursday which read, "Dear Lord, can we end this bulls#t once and for all. Amen."

The junior Spears has been criticized by her older sister's supporters for keeping silent on the conservatorship while appearing to benefit from it.

In June Jamie Lynn took to her Instagram stories to defend her silence.

"The only reason I haven't before is because I felt like until my sister could speak for herself and say what she felt she needed to say publicly, it wasn't my place, and it wasn't the right thing to do," she said.

"If ending the conservatorship... or whatever the hell else she wants to do to be happy - I support that."

"I have nothing to gain or lose either way," she said.

Although Jamie Lynn Spears has denied ever taking money from her sister, fans have pointed to court documents that show the singer paid for numerous flights taken by her younger sister. Jamie Lynn was also named as a trustee of the singer's estate last year.
