About this sound
This is a 12-second spoken clip in Portuguese of the Gossip Girl sign-off, where the unseen blogger asks who she is, refuses to reveal her secret, and closes with kisses. It feels cheeky and conspiratorial, like being let in on Upper East Side drama. It comes from the television series Gossip Girl.
