Los Angeles: Popstar Britney Spears and her younger sister Jamie Lynn Spears are reportedly planning to have a double wedding.
The 28-year-old singer wants to tie the knot with her lover Jason Trawick and Jamie is keen to marry her on/off beau Casey Aldridge, Ok! magazine reported.
Britney is said to have discussed the idea with her sibling when the duo attended a music concert of Lady Gaga here earlier this month.
"Britney was half-joking about creating a huge, over-the-top Hollywood affair at first. But when the two couples went back to her California home, the sisters couldn`t stop talking about it," a source said.
"They`re continuing to discuss details about the big day and are determined to ensure it is the wedding of the century," the source added.
The `Toxic` hitmaker has tied the knot twice before, to Jason Alexander and Kevin Federline, the father of her two sons, four-year-old Sean Preston and Jayden James, three.
Her sister Jamie Lynn has a two-year-old daughter, Maddie, with Casey.
