Of course, Leslie was sure to provide a disclaimer that read: "Don’t read into this kids. It’s not a spoiler or a hint. This was just me goofing around after stunts today captured by the one and only."

Leslie made her appearance as Donna in the latter half of Titans Season 1. While just a recurring character in the first season, it has been reported Donna will play a larger role in the second season.
