The Gangnam Style hitmaker and the rapper have teamed up for new "party anthem" Hangover and they'll debut the track during a special prime time airing of U.S. talk show Jimmy Kimmel Live! on Sunday.
The video for the new track will then be posted on Psy's YouTube channel and on Kimmel's website.
The song will be available as a digital download the following day (09Jun14).
Just days ago (30May14), Gangnam Style officially became the first music video to pass two billion views on YouTube.
Commenting on the feat in a statement released over the weekend, Psy wrote: "2 billion views... they are very honorable and very burdensome numbers. With appreciation, I will come back soon with more joyful contents!"
