Britney Spears has responded to her sister Jamie Lynn Spears’ interview.

Britney accused Jamie of using her to try and sell her upcoming book.

Britney said she “got really sick last night” with a fever of 104 degrees. She said she asked security to go and get her some pain medication to treat a headache but was told that security couldn’t leave the property.

“I watched it with a 104° fever lol and it was actually kind of nice having a fever so high cause I had to surrender to not caring,” she said of the interview. “I just couldn’t give a f*ck but my head hurt so bad.”

“She was never around me much 15 years ago at that time …. so why are they even talking about that unless she wants to sell a book at my expense ??? REALLY ???” she continued.
