Cheetah recently uploaded an Instagram post sharing the details of her upcoming song, titled "I'm Your Mother," set for release on December 18 at 12pm (KST). The image shows an outline of Darth Vader whose most famous line is "I'm Your Father," so the title seems to be a play on that. It also matches the release of the new Star Wars movie. Besides that, it's hard to gather what the concept or the style of this new song will be just from this one post, so I guess we'll have to sit tight until the rapper shares more details or starts releasing teasers. 

What a welcome surprise just in time for the holiday season, eh? And just four months after her last song, "My Number," at that!
