Any confusion about Kacey might have been because her former boyfriend's name was Misa. Her husband (since late 2017) has the slightly less gender-ambiguous name of Ruston.
Meanwhile Jenny's new single is already getting frequent airplay on the local alternative station here in L.A. Her Austin City Limits appearance in support of Voyager was one of the two or three best performances I've seen on ACL in years--so I have very high hopes for the new album.
