Yes, Superman is currently dating Wonder Woman...and maybe not just in the comics.
Just over three months ago, rumors began that mixed martial arts fighter-turned-actress Gina Carano was going to be Wonder Woman in the upcoming 2015 Justice League movie after Carano was spotted with Man of Steel star Henry Cavill at an unveiling for McClaren Automotive. This speculation followed on developments in DC Comics' Justice League series where the characters of Superman and Wonder Woman abruptly began showing romantic feelings towards one another.
Well, Carano and Cavill officially debuted as a couple yesterday at the Critics' Choice Awards in Los Angeles by appearing together on the red carpet. The two presenters were spotted holding hands and E! News reported that the couple have been dating since September after Cavill ended his relationship with fiancee Ellen Whitaker.
Rumors persist that Wonder Woman could make a surprise appearance in Man of Steel, perhaps in a post-closing credits cameo similar to the recent Marvel cinematic universe films. If so, there may have been Warner Bros. screen tests to see if Carano had chemistry with Cavill, which could've been where the two first met one another.
Even if the Man of Steel cameo doesn't happen, it's possible Carano tested with Cavill for Justice League just to see if she was right for the role of Wonder Woman. Man of Steel director Zack Snyder made comments back in November that it made sense for Cavill to reprise Superman for Justice League. "I don't know how Justice League is going to be handled," said Snyder, "but Man of Steel exists and Superman is in it. I don't know how you'd move forward without acknowledging that."
