After Jamie Lynn said that the Toxic singer was "erratic, paranoid" and "spiraling" during a series of ABC News interviews last week, Britney took to Instagram Thursday (Jan 13) to air her grievances about her sister, explaining that she had a fever of 104 degrees while the latest events transpired.
"It was actually kind of nice having a fever so high cause I had to surrender to not caring," Britney, 40, wrote in a series of Notes app images posted Thursday on Twitter that appeared to accuse her sister of being an opportunist.
