Adele had a date night with her boyfriend in London on Friday, and Lady Gaga provided the entertainment.

Adele and Simon Konecki checked out an intimate, Belvedere Vodka-sponsored performance by Gaga at the club Annabel's, according to People magazine. They entered through the back door.

As you'd expect, they didn't bring their son, Angelo, to the event.

A source says of Adele, "Her skin was radiant and she seemed very happy to be out," adding, "Simon kissed Adele on the cheek and had his arm around her waist at many times of the night."

Sting and Harry Potter actress Emma Watson were among the other stars who witnessed the performance.

People notes Gaga's set list included "Artpop," "Dope," "Do What U Want" and "Poker Face."
