After a long three-year hiatus, Adele finally released new music Friday morning. The song, called "Hello," is the first single off the singer's highly-anticipated new album "25," which will be released on Nov. 20. Many celebrities took to their Twitter accounts to congratulate her on the beautiful new song and music video that she also released.

Everyone from Katy Perry to John Stamos to Lena Dunham could not contain their excitement over the new Adele music, just like the rest of the world.

"Stunning! Love the new #Hello by Adele. '25' drops on Nov. 20," Stamos tweeted.

"Sun is shining because Adele," Dunham wrote on the social media site.

Adele previously said of the new song that it was a "massive breakthrough" for her album "25" and that she always knew it was going to be her first single, as HNGN previously reported.

"It happened quickly when I was writing it, so I felt that was a good sign, but also it's incredibly conversational. I didn't want to come back with some spectacular point. I didn't have any points to prove," she said of the song.
