Pamela Anderson Divorce -- Pam Files for Divorce from Rick Salomon ... Again

Pam Anderson is pulling the plug on her marriage to Rick Salomon ... TMZ has learned.

This will be Pam's second split from Salomon, whom she married in 2007 and stayed with all of 2 months. She got the marriage annulled. She was also married to Tommy Lee and Kid Rock.

Pam went public in January, saying she married Salomon again.

Interesting timing ... Salomon, a world-class poker player, won $2.8 million in the World Series of Poker Big One for One Drop last Tuesday. Pam filed on Thursday, so under the community property laws she gets half by the skin of her teeth ... unless there's a prenup.

In case you don't recognize Salomon, he's the one who co-starred with Paris Hilton in the famous sex tape, "One Night in Paris."

2:00 PM PDT -- Pam's not publicly known for being religious (more like the total opposite) ... but she just posted this message on Facebook. It appears to be a prayer from Rev. Maryum Morse from the Agape Center.
