Supergirl Will Not Crossover With Arrow And The Flash Says CBS Head

From the ongoing TCA event, CBS Entertainment president Nina Tassler has squashed fans hopes that Supergirl may crossover with the DC Comics television series airing on sister network The CW, including Arrow, The Flash, and Legends of Tomorrow.

As tweeted by USA Today's Gary Levin, the most you'll see of these characters during each other's time slots is during commercials.

Don't look for crossovers between #Supergirl and #Arrow, on sibling networks. But they'll run promos for each other. #TCA15

Tassler has been vocally doubtful of the crossover potential between networks from the start, and Greg Berlanti, executive producer on all four of these DC Comics series, has also cautioned fans to not get their hopes up.

Supergirl premieres Oct. 26 at 8:30 p.m. ET on CBS.
