Melanie Scott "Minty" Lewis is a storyboard artist, comic writer and voice actress for Regular Show, who provided the voice of Eileen. She initially worked as a storyboard artist for four episodes in Season Two, before leaving the show to raise her newborn child. Despite leaving as a storyboard artist, her pitch for "Do Me a Solid" convinced creator JG Quintel to hire her as the voice of Eileen. Minty later returned as a storyboard artist in Season Five, and remained on the team until the show ended in 2017.

Outside of Regular Show, she has also worked as a voice actress for other Cartoon Network properties, such as "Adventure Time", "Infinity Train" and "We Bare Bears", the latter of which she wrote an episode for in 2018. She additionally worked as a writer for the first season of JG Quintel's later show, "Close Enough".
