The duo has been hired for the shows's season three following the departure of Ali Adler, reported Deadline.
Adler served as co-showrunner for the first two seasons of the DC Comics-inspired series. She, however, will remain involved as an executive consultant on "Supergirl".
Queller and Rovner will join Andrew Kreisberg in the new showrunner team. Kreisberg, who co-created the series along with Adler and Greg Berlanti, has also served as executive producer since the beginning of the show featuring Melissa Benoist.
