Shanna Moakler Rings In the Ex

The only thing Shanna Moakler likes more than fighting with ex-husband Travis Barker on MySpace ... is getting back together with him.

The 33-year-old former beauty queen hung out with Travis this weekend and actually wore her wedding ring. I love you -- for now.

If you think it's hard keeping up with the status of Shanna and Travis' relationship, imagine what their children must think.
