Playmate Karissa Shannon may have had a change of heart when it comes to fighting the release of her sex tape -- and it all comes down to her suspicious visit yesterday to Vivid Entertainment's headquarters.
Karissa and actor Sam Jones III -- her boyfriend/sex tape partner -- were spotted outside of Vivid's office in L.A. yesterday afternoon ... where Sam confirmed they just had a meeting with Vivid boss Steve Hirsch.
As for what the meeting was about -- Sam told our cameraman they were "exploring all of our options" ... then quickly covered his bases by saying, "Especially our legal options."
