Yup, she was married to Jeffrey Willerth from 1999 - 2008 (IMDB says he only played Kosh in In The Beginning)and now she's with JMS (Not sure if they got married or not) and they are working in his new Production Company together
I think perhaps they're not dating any longer. Regarding the photos - the reunion photo was taken at a dinner party JMS threw at the B5 reunion at Phoenix Comic-Con this past May. I took to pic of Pat at this year's San Diego Comic-Con. Pat's a sweetheart.
