Britney Spears has reportedly changed the custody terms in her will.
The 'Toxic' singer has allegedly changed her will to ensure her mother Lynne never gains custody of her grandsons, 22-month-old Sean Preston and 10-month-old Jayden James.
Britney's teenage sister Jamie Lynn is now set to inherit the star's estate and custody of her sons when the singer dies, according to National Enquirer magazine. Britney also reportedly stipulates in the new will that her cousin Alli Sims will look after the boys if she dies before 15-year-old Jamie Lynn turns 21.
Relations between Britney and Lynne allegedly turned sour after the 'Lucky' singer felt her mother forced her into rehab. The 25-year-old visited Lynne on the set of Jamie Lynn's TV show, 'Zoey 101', last week and allegedly handed Lynne a legal order banning her from seeing her grandsons while she is on any form of medication. Britney also reportedly hired a private investigator to record phone calls between Lynne and the singer's estranged husband Kevin Federline.
In one conversation, Lynne is said to arrange to meet Kevin and the boys,saying: "I have to be careful that Britney doesn't find out!"
Britney is also said to have presented Lynne with a hate-filled poem. A source said: "In the poem, titled 'Dear Mama', she wrote that she didn't have a mom anymore and she couldn't imagine a mother doing what she did to her child. Britney gave the poem to her mom and said, 'Here Momma, I just wanted to see your face.' Then she got into her car and drove off. Lynne went into the trailer and broke down in tears." |
