They had a romantic date that brought them to the park below Griffith Observatory for a picnic. After their meal, Quentin gave his girlfriend a blindfold and noise-canceling headphones (“kinky,” Adele remarked) and led her to the show.

In a new teaser for the Grammy-winning singer’s upcoming interview with Oprah Winfrey, Adele is giving viewers a feel for her “One Night Only” concert TV special, which heralds her “comeback” after a six-year hiatus. “You’ll hear a lot of older songs, and then four new songs,” the British balladeer says in a new clip released Wednesday.
