Jamie Lynn and Britney Spears: A Brief Timeline of Their Relationship

Britney Spears and her sister Jamie Lynn have been engaging in a social media war of words following the latter's appearance on Good Morning America to promote her new autobiography.

After Jamie Lynn referred to her sister's behaviour as "erratic," "paranoid" and "spiraling," Britney took to Twitter to ask, "why are we even talking about that unless she wants to sell a book at my expense."

After Britney said of her sibling, "she never had to work for anything. Everything was always given to her," Jamie Lynn released her own response on Instagram. The Zoey 101 star said: "I've worked hard since before I was even a teenager, and I've built my career in spite of just being someone's little sister."

Before this very public falling out, the actor and the "Toxic" singer have had what seemed to the public to be a fairly strong relationship, though one that has turned sour following Britney fans turning on Jamie Lynn following some of her statements over her sister's conservatorship battle.
