Brandi Carlile and her wife, Catherine Shepherd, first struck up a relationship over the phone - but it wasn't long before they hit it off in person as well. The Grammy winner and the U.K. native met in 2009 while Shepherd was working for Paul McCartney, coordinating his charity work. Carlile and her future wife spoke over the phone for a year before finally meeting in person. The Highwomen member has a distinct memory of the moment when she realized she thought of Shepherd as more than a friend. Carlile was on tour in Vermont when Shepherd came to visit her on her tour bus.
