The Flash and Supergirl are very cute on the set of their crossover episode

Yes, we got a brief glimpse of Supergirl on The Flash the other night, but the real crossover event won't happen until March 28, on Supergirl. Until then, Flash's Grant Gustin and Supergirl creator Ali Adler shared a few photos of the shoot on Instagram:

Gustin took a moment to complain about his on-set accommodations on The Flash compared to the relative luxury of the Supergirl set, with its CBS money:

 

Hey Flash producers… I've already got a fancier chair on Supergirl than I've got on Flash. Just saying…

And even the combined powers of our two heroes couldn't stop an evil villain from (photo)bombing their selfie:

 

Those two emblems look pretty good together… @melissabenoist
