lips sealed
Keeping the secret
To keep one's lips sealed is to maintain secrecy or refuse to divulge information: My lips are sealed—I won't tell anyone about the surprise party.
The phrase often appears as a promise of discretion or a refusal to talk: She kept her lips sealed about what happened that night.
Sometimes used as a standalone assurance: Lips sealed.
