Britney SpearsBritney Spears has reportedly updated her will to take account of her current feud with her mum, Lynne Spears.

According to the Mirror, the singer will now leave the money intended for her family to her little sister Jamie Lynn instead - but Jamie Lynn doesn’t like being pulled into the middle of the fight.

A source is quoted as saying: “Britney is using her money to pit her sister against her mom. Jamie Lynn loves them both - and doesn’t know what to do.”

Another source told Star magazine that Jamie Lynn is generally annoyed at how Britney is treating their mum: “Jamie Lynn and Britney have always been close, but Jamie Lynn thinks Britney is being cruel, especially after everything their mom did for her. Jamie Lynn wants it to stop.”

The magazine also reports that Britney has been living to excess recently: “drinking heavily again, binge shopping and eating like there’s no tomorrow.”

An inside source told the publication: “On several occasions, I have seen her pouring alcohol into energy drink cans.”

“Britney [also] requests that her alcohol be served in carafes rather than in bottles. Once, a waitress made the mistake of bringing her a bottle. Brit grabbed her arm and told her she couldn’t be seen with it.”

Britney insists her mum Lynne, along with her manager at the time Larry Rudolph and estranged husband Kevin Federline, forced her to go into rehab in Febuary to deal with alcohol and drug problems, but the singer claims post-partum depression and anxiety were really to blame for her breakdown.
