Britney Spears is not here for Jamie Lynn’s new book & writes a shady post...

Britney Spears has subtly shaded her sister Jamie Lynn Spears over an awkward book title change.

Jamie announced her upcoming memoir, ❝Things I Should Have Said❞ earlier this week.

The 30-year-old sister of Britney Spears revealed to her 2.2 million followers she had changed the title after receiving some serious backlash. The original title of her memoir was called, ‘I Must Confess: Family, Fame, and Figuring it Out.’ The line ''‘I Must Confess" is a lyric from Britney’s debut single 'Baby One More Time.' The title was then changed after she encountered harsh criticism. Now it appears Britney has spotted the title change and took to Instagram to throw some subtle shade. Britney has a very strained relationship with her sibling after she hit out at her family for not helping her or speaking out during her conservatorship nightmare. Britney has taken shots at her younger sister multiple times on the social media platform (see screenshots below).

Britney should write a memoir of her own and call it 'Toxic' or 'My Prerogative,' then do a 2-hour special with Oprah to promote it if she wants to achieve that master revenge. Not sure how much she would be able to reveal due to certain legalities but one things for certain, it would be one hell of a bombshell memoir.
