She's lived in the shadow of her world famous sister her whole life, but Jamie Lynn Spears could spill all about their Toxic relationship on I'm A Celebrity.
Jamie Lynn has painted Britney as both a "mother figure" and distant, troubled child who locked her in a room with a knife when she was 12.
Despite enjoying stellar fame, Britney is said to envy Jamie Lynn’s childhood - made easier by the millions brought in by herbig sister.
Britney says her hard work meant her sibling never had to work for anything, while she grew up poor.
Tragically the sisters have barely seen each other over the last two decades and it’s believed Britney has had little contact withher nieces.
A source said there is a part of Britney's heart which would have loved to have been a loving, caring aunt.
An insider warned that Jamie Lynn, who is filming a movie follow-up to her Zoey 101 show, could damage her return to acting if she spills about her sister's life.
