has posted a 19-second clip off PornoTube that’s allegedly from a Britney Spears sex tape featuring her in dark hair giving Kevin Federline a blowjob. I’m not an expert on Britney Spears’ face or K-Fed’s penis so I can’t make any claims to its validity, but you can check out the 100% NSFW clip and judge for yourself. Although be warned, because if it is real then after seeing it you will never again in your life be able to honestly say you haven’t seen Kevin Federline’s naked penis.
UPDATE: A ton of readers reached into their encyclopedic knowledge of porn and wrote in saying this isn’t Britney, but just some random amateur girl from a super long time ago. Yay for perverts!
