Christina Slams Britney As "trailer Trash"

Pop diva Christina Aguilera has fired off a tirade against bride-to-be Britney Spears - accusing her of acting like "trailer trash".

The Dirrty singer - who is allegedly engaged to long term love Jordan Bratman - reportedly told American tabloid US WEEKLY she was horrified to hear Britney had bought her own engagement ring, and thinks it looks cheap.

On Britney's forthcoming wedding to dancer Kevin Federline, Christina says, "I can't believe that girl bought her own engagement ring! I've seen it, up close. It looks like she got it on QVC.

"I know Britney. She's not trailer trash, but she sure acts that way."
