Britney SLAMS Ex-Hubby -- 'Kiss My Lily White Ass'

Britney Spears just lashed out against her ex-husband Jason Alexander -- and both of the publications responsible for publishing a phone call allegedly featuring her voice -- advising them all to "Kiss my lily white southern Louisiana ass!"

As we previously reported, Britney claims the person on the tape is not her -- and her lawyer has already threatened legal action against everyone involved in its release.
