Glamour model Pamela, 47, originally married Rick in 2007, but just two months later had the union annulled.
Anderson and the film producer then rekindled their romance in 2013, with Pamela confirming early this year that they had indeed walked down the aisle once more.
But on Thursday, Pamela filed legal papers to end the marriage, just days after Salomon won $2.8 million in the World Series of Poker Big One for One Drop.

Anderson, who recently revealed she was gang raped as a youngster, has also been married to Tommy Lee and Kid Rock, whilst Salomon became famous for starring in Paris Hilton's sex tape 'One Night in Paris.'
According to reports, when Pamela was spotted in Malibu this weekend she was notably without her wedding ring, and Rick also did not show up to an award ceremony where Pamela was honoured in June.
So far there has been no response from team Anderson, though the star has hinted at troubles on her Twitter page, writing: 'Closing the open hand…hardest thing to do.'
And on July 6 she added: 'I no longer have the time for anyone or anything that can not give emotion, time and love, honestly, freely and with sincerity…my beautiful, soulful, mentor BB [Brigette Bardot].'
