Britney Spears and her younger sister Jamie Lynn are planning to have a grand scale double wedding, according to a report in OK! Magazine. Britney has settled down with her former manager, Jason Trawick, and Jamie Lynn is raising daughter Maddie Briann with her on again/off again fiancee Casey Aldridge and reports have surfaced in recent weeks about a wedding for the elder Spears.

The magazine claims that what was initially a half-joke by Britney turned into actual wedding plans that include “their kids [as] ring bearers and the flower girl,” the sisters walking each other down the aisle, and “fantasy guests” such as President Barack Obama, Oprah and Lady Gaga. A source told the magazine that when “Jason said it would be bigger than a royal wedding, Britney’s eyes lit up.” –ANDREW BANKIN
