Forget Travis and Jason Kelce singing Bob Seger ... now there's new video of Ray Romano singing karaoke at the same celebrity golf tournament ... and he's covering some Eminem!!!
The comedian grabbed the mic and took the stage at the American Century Celebrity Golf Tournament in Lake Tahoe ... rapping Em's hit "Lose Yourself" as only Ray could.
Ya gotta see the video, which is now making the rounds on social media .
