Well, not an official one.

A rumor for a Luigi 2DS we reported on earlier this week has been debunked.
The rumored 2DS in question was actually made by Matthew Wiggins. He made it for his website Rose Colored Gaming, where he customizes and sells modified game systems and accessories, mainly for Nintendo handhelds. The news that it was only a custom came from the YouTube video from Wes De of Second Opinion Games.
