Riley Giles and Bree Tierney Slug It Out Via MySpace

We haven't had a good MySpace fight since Jenna Jameson and Jay Grdina.

So imagine our excitement when we discovered that Lindsay Lohan's boyfriend and his former flame were going at it online.

Loyal celebrity gossip followers know all about Breanna Tierney by now.

The ex-fiancee of Riley Giles supposedly spilled the sordid beans of Riley and Lindsay's relationship to The National Enquirer this week.

And, by the looks of this MySpace exchange, Giles is none too pleased about that.
