Jessica Simpson posted the following snapshots (courtesy of Ken Paves) on her Twitter account last night, and we're not sure if it's a wig or what, but we can't imagine the pop star would chop off her luscious locks!

Jess tweeted, "In flight hairdo fun!" and "Carol Brady who?" so we're thinking this is just a belated April Fools prank...
