Playboy has offered the two beauties $1 million to pose nude together in the magazine.
Although both Anderson and Richards have previously worked with Playboy, the creator, Hugh Hefner is determined to reunite the women for the January 2008 issue.
A source told the Globe, "Neither Pam nor Denise has committed yet, but they’re seriously considering it."
Anderson has appeared in Playboy twelve times, while Richards was in the December 2004 issue.
The two actresses became good friends after filming Blonde and Blonder together.
