“If you make a noise, I’m gonna kill you,” the “Easy on Me” singer joked to fans.

When the couple reached the front of the crowd, Quentin removed Ashley’s headphones and told her to take off her blindfold. The stunned woman looked into the audience, which was filled with celebrities such as Melissa McCarthy and Lizzo, as Quentin dropped to one knee.

After Ashley accepted Quentin’s marriage proposal, Adele emerged and congratulated the pair, telling them to sit in the front row. McCarthy then handed Ashley a glass of champagne as Adele sang “Make You Feel My Love.”
