I'm pretty sure they are still married. She met Vince during her House of Love album recording, I think back in 1993 or 1994. Vince Gill sang the duet song, House of Love with her on her album and did a House of Love music video with her. Supposedly they fell in love and had an (cough cough) affair while she was still married to her 1st husband, Gary Chapman (no relation to Steven Curtis Chapman). I am not too thrilled she had this supposed affair while she was still married to her 1st husband. Vince was also married to his 1st wife while he and Amy met as I recall.
I do like alot of Amy's older music from the '80s and liked her in that Three Wishes tv show that she was on last yr on NBC. I'm not a huge fan of Vince Gill, tho.
