Adele, released "21" four years ago which sold more than eleven million copies in the United States, according to USA Today. Now, it seems that the British singer is back with a new album.

A video was uploaded Tuesday on YouTube by Hollywood Today G of a never-before-heard song with lyrics. If you listen closely, you will hear that the voice singing in the background definitely belongs to Adele.

The lyrics say, "Hello, it's me. I was wondering if after all these years you'd like to meet to go over everything."

The lyrics continue with: "They say that time's supposed to heal ya, but I ain't done much healing."

On that very same day, Hollywood Life learned that the screen went black during "The X-Factor," and those lyrics suddenly appeared on the TV screen.

Another video, apparently with the same content, was uploaded on Twitter by @sentimental666, captioned: "ADELE IS THIS U WHAT DOES THIS ADVERT MEAN AHH IVE MISSED U."

The 30-second clip caused frenzy over fans on social media. Other than the comments of the Adele fanatics, expressing their too much excitement over the "Skyfall" singer's new album, the post itself got retweeted so many times.

"U'VE NO IDEA HOW LONG I'VE WAITED FOR THESE 30 SECONDS, H*LY CR*P THE B*T*H IS BACK!" @FreedAdkins replied to the comment.

There was one who said it was sensational, and there were others who commented that they were about to cry out of excitement.

Whether this clip of the "Someone Like You" singer belongs to her new album, reportedly entitled "25," remains to be confirmed. There are no official statements yet from the sensational songstress' representative.

Adele is also mum about this subject. Her last tweet was in August, and that had nothing to do with her new album.

Could this song be really a part of Adele's new album? Sound off your comments below.
