Adele helped pull off a couple's surprise engagement on her TV special: 'Look at her, she's so in shock!'

• Adele stopped her "One Night Only" concert to help a couple get engaged.
• Adele got her audience to be quiet while a fan brought his long-term girlfriend onstage to propose.

Adele helped a couple get engaged during her concert TV special.

During Adele's promotional tour for her coming album "30," the British singer performed some of her greatest hits and songs from the new album at the Griffith Observatory in Los Angeles at the end of October.

The concert, which featured stars including Lizzo, Seth Rogen, and Melissa McCarthy, was recorded as part of a two-hour special called "One Night Only" that aired Sunday on CBS.

During the concert, Adele got her audience to play along with a surprise proposal onstage that had been orchestrated beforehand. Adele explained that a couple, Quentin and Ashley, had been together for seven years and she wanted the audience to be quiet so that Quentin could surprise Ashley and propose on the stage.

"I need every person to be really quiet, all right? If you make a noise, I'm going to kill you," Adele added before the lights were dimmed so Ashley couldn't see where she was.

After this, Ashley, who was blindfolded, was led to the stage by Quentin. She then took her blindfold off and saw Quentin on one knee.

"Thank God, you didn't let me eat. I would have thrown up," she said during Quentin's proposal speech.

After Ashley said she would indeed marry Quentin, Adele appeared from the shadows, stunning the new bride-to-be.

She asked the engaged couple to sit in the front row near Lizzo and McCarthy and said: "Thank God she said yes because I didn't know who I was going to sing this song to next. You or him, oh, my God!

"Look at her, she's so in shock! Oh, that was lovely. I had a little cry."

Adele sang her next song dedicated to the newly engaged couple, "Make You Feel My Love."

Adele's new album "30" is scheduled to arrive Friday.
