Call it The Fast and the Fabulous.

Sister networks CBS and The CW have announced that Grant Gustin will be bringing his red-suited Barry Allen from The Flash over to Supergirl for a guest spot on the March 28 episode of the CBS series.

Calling the crossover "something that we have dreamed of happening since we starting making Supergirl," executive producers Greg Berlanti and Andrew Kreisberg went on to thank the fans and media for their interest in these two meeting up, as well as the two networks, Gustin, Warner Bros. and DC Comics for super-teaming to make the scheduling possible. After all, The Flash films in Vancouver and Supergirl shoots in L.A., so this required a lot more logistical trickery than when the Scarlet Speedster pops up on Arrow, which is basically produced in the soundstages across the street in British Columbia.

At the start of the season, there was much talk about whether we'd ever see Melissa Benoist's Kara Danvers/Supergirl cross paths with any of the other DC Comics heroes on TV, and the party line was mostly, "If there's a way it can work, maybe." Now that they have found a way, this mashup could give Supergirl a supersized boost in the ratings, which would go a long way towards a Season 2 pick-up.

Supergirl airs Mondays at 8/7c on CBS.
