Britney Spears is estranged from her little sister Jamie Lynn Spears after refusing to be maid of honor at her upcoming nuptials.

“All she wants to do is live off my fame,” Britney has told a friend. “She just wants her famous sister at her wedding to show off to her friends. She doesn’t care about me.”

A new tabloid report alleges that sixteen year old mother-to-be Jamie Lynn is set to marry boyfriend Casey Aldridge in a low-key ceremony before the birth of their baby this June. But Jamie Lynn’s twenty-six year old big sis told the young actress that “hell would freeze over” first before she stood up as maid of honor at Jamie Lynn’s wedding this summer.

The tab claims Brit is still humiliated that she found out that she was going to be an aunt from an article in OK! Magazine, rather than from her sister’s own lips.

“Although Britney had it out with her sister at the time, she’s been simmering with resentment ever since. She believes that Jamie Lynn’s broken the close bond the two have always shared and is using Britney’s fame to make money,” a family friend snitches.

“When Jamie Lynn asked her, Britney laughed sarcastically down the phone. She told her that hell would freeze over before she’d stand as her maid of honor then hung up on her.”
