Britney Spears had some harsh words for her sister.

She posted a new IG reel on Tuesday afternoon.

Jamie Lynn’s memoir went public earlier that day.

“In life a lot of people say ‘DO I MATTER ????'” she began.

"Try eating alone for 4 months morning … noon … and night Jamie Lynn,” she wrote.

Britney said she would be very interested in seeing Jamie’s “very pretty face…”

“…in the setting I was forced to be in.” It’s unclear what setting she means.

"I didn’t get to cry,” Britney continued. “I had to be strong … TOO STRONG !!!”

Jamie Lynn has yet to respond to her sister’s latest message.
