The only source that confirms it is Deadline, who says that it got it's information from "sources close to the two shows". How many times have websites made that claim and ended up spreading a false rumor? The lack of apostrophe in the title can mean anything. And Supergirl's cameo in the vortex last week? The DC Multiverse has a lot of similar universes. Characters from our Earth-1 and Earth-2 are played by the same actors. So what are the chances of two universes where Supergirl looks like Melissa Benoist? We need real confirmation from the shows' creators. And they're closing the breaches so how is Barry going to reach Supergirl's universe? Have I mentioned how out-of-nowhere it would seem in the Supergirl show to have a speedster coming through an interdimensional portal? Sean here's your "confirmation": https://twitter.com/GBerlanti/status/697225319426621440

They literally showed a scene from the Pilot during that glace of Supergirl's Earth.
