Welcome Connie! We're glad to have you here!
We are glad y'all FINALLY got to see the Inside Fame episode up there in Canada! If you do a search on the Main Forum there are some threads there from when it aired in the U.S. that you might enjoy reading.
To answer your question, no Garth & Trisha are not married, Garth did make that very leading comment, which made everyone wonder if perhaps they were engaged, but they say they aren't. So we're gonna take their word for it - for now!
Hope you'll stick around the Planet and post lots. There's a Welcome Forum where you can introduce yourself too!
