— -- Pink and Ellen DeGeneres are good friends, and the singer is a frequent guest on the show.

Now, she's recorded a theme song for the new season of "The Ellen DeGeneres Show."

"What better way to launch Season 13 than with a new song that @Pink wrote just for me? Today’s the day!" DeGeneres tweeted, along with a video of Pink recording the song -- called, yes, "Today's the Day."

The singer's 4-year-old daughter Willow also makes a guest appearance in the video.

"Somebody please stop the clock/Oh, Never let this day stop," Pink sings. "Today's the day I been waiting for/Tomorrow won't come after all/Yesterday's so far away/I guess today's the only day."
