Carrie Prejean Sued -- Crosses PR Flack

Carrie Prejean isn't just opposed to gay marriage, she's also opposed to paying more than $64,000 to the "Christian-focused" PR firm who helped her out, this according to a new lawsuit.

The group -- A. Larry Ross Communications -- claims Prejean contacted them back in April, 2009 and logged "hundreds of hours" helping Prejean spread her "biblically correct" message.

But according to the lawsuit, filed earlier this month in Texas, Prejean's actions were the opposite of Christian -- because she never paid the $64,857 bill.
