Britney Spears has refused to attend her younger sisters alleged wedding. Sources say the singer’s pregnant 16-year-old sister Jamie Lynn Spears is set to marry her 19-year-old boyfriend Casey Aldridge before their child is born.

Sources say Jamie Lynn asked Britney to be the maid of honor at her ceremony but the singer told her “hell would freeze over” before she would attend the wedding.

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