Lady Gaga is ready to pick up the telephone again . . . 15 years later.

Gaga took a lie detector test for a new Vanity Fair video, and in it, she was asked if she still plans to continue her and Beyoncé’s “Telephone” video, since it ends by saying “to be continued.” She said she does, but she’s not sure when. Then she was asked if Beyoncé will be in the video. She smiled and said simply, “Maybe.”

Lady Gaga has teased the possibility of a sequel to her Telephone music video featuring Beyoncé. Released in 2010, the final shots of the nine-minute-long film show the superstars driving through a desert while police sirens wail in the background.
