This article fails to mention it, but other articles go into a bit more detail regarding ex-wife Jeri Ryan. They say that she lost her feelings for husband Jack, and she fell in love with another man, following the "public sex" incidents.
What the article fails to mention is that, during or shortly after the time of these incidents, Jeri Ryan was just joining the cast of Star Trek: Voyager as "Seven of Nine". She started in the 1997-1998 season. And the other man, who she was reported living with as early as 1999, was Star Trek Executive Producer Brannon Braga.
My, that was quick. And convenient.
She is now married to Brannon Braga.
