Jenna Jameson, Jay Grdina Duke it Out Over MySpace

Jenna Jameson has lost a lot of weight recently. The porn star will readily admit as much.

But it's not because she's on drugs and it's not because she has an eating disorder like certain anonymous people named Nicole Richie.

According to her very own MySpace account, the most famous adult film star in the world is going through .... a divorce. So we guess it makes sense she's lost so much weight. Here are Jenna's own words on the matter:

I feel like I need to address the weight rumors that have been swirling for a few months now. This saddens me... only because, everyone that is judging me... has absolutely NO idea what is happening in my life. People are hateful and accuse me of being a drug addict, or an anorexic. Does anyone seem to remember the fact that I am going through a nasty divorce? It has been weighing heavily on me.

Of course, the ex in question - Jay Grdina - shot back. On his MySpace page. Here's one excerpt of his long rant:

The saddest point about all of this is that most people have to hit rock bottom b4 they realize this simple truth....this is heart breaking to everyone that loves and supports that person ...

Jay could go on and on. And he does.

But this has obviously been a tough week for the guy - first, Shanna Moakler gets back together with Travis Barker; and then Jenna goes on the attack.

In the grander scheme of life, though, we hope Reese Witherspoon is now careful. Eat through the divorce pain, honey.
