Adele teases 30-second song, Twitter goes crazy

UNITED KINGDOM-- Grammy-winning artist Adele may have come out of the blue, uninvited to surprise her fans in a mysterious 30-second ad.

Adele fans have taken to social media a 30-second song played during a commercial break for 'The X Factor' in the UK on Sunday.

The short snippet didn't mention the artist or title, but Adele's powerful vocals are obvious. The ad was accompanied with lyrics of a song, saying:

Hello, it's me
I was wondering if after all these years
You'd like to meet, to go over everything
They say that time's supposed to heal ya
But I ain't done much healing…

It has been almost five years since Adele released her album "21," for which she won six Grammys. Adele-- or her label-- is yet to confirm the rumors. But not surprisingly, social media users have taken to Twitter the album speculation on when, or if, her new music might drop.
