According to a source who wishes to remain anonymous because of her own involvement in the scene, Vicki's ex-husband, Donn Gunvalson, has been spotted at Freedom Acres swingers club in Devore, California with an unidentified woman recently.
"I recognized him immediately, and once I started talking to him he introduced himself as Donn," the insider revealed.
"He went to the back room with the woman he brought and they were engaged in public sex."
Freedom Acres is recognized as the largest 21+ swingers club in the Los Angeles and Orange County area and a yearly membership is required to enter.
According to their website, the club also features a "pool table, an oversized hot tub, dance floor with raised stage complete with a pole for dancing and many TVs throughout the club showing XXX movies."
The insider tells RadarOnline.com she's seen Donn at the club a few times, although he typically just has public sex with his partner and doesn't engage others.
"I've never seen him have sex with anyone other than who he brings," the source said.
"He just seems to really enjoy public sex and the vibe of the club."
