(Cover) - EN Showbiz - Britney Spears is considering having a double wedding with her sister Jamie Lynn Spears.

It has been reported the siblings were at a Lady Gaga concert in Los Angeles earlier this month when Britney came up with the idea. Britney feels ready to tie the knot with Jason Trawick, while 19-year-old Jamie Lynn is thinking about marrying her on-off boyfriend Casey Aldridge.

Although 28-year-old Britney wasn’t being serious when she originally suggested the double wedding, the girls continued to discuss the idea and are now giving it some proper thought.

“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,” reports the American edition of OK! magazine.

Now Britney and Jamie Lynn are continuing to discuss details about the big day and are determined to ensure it is the “wedding of the century”.

Britney has been married twice before, to Jason Alexander and Kevin Federline – the father of her two sons, four-year-old Sean Preston and Jayden James, three.

Jamie Lynn has a two-year-old daughter, Maddie, with Casey. The pair called off their engagement in March 2009 before splitting up in February, but reunited earlier this month. (C) Cover Media
