keep (something) on the hush
To keep something in a state of secrecy or minimal public knowledge; to allow something to be known only by a select few people. I need to tell you something, but you have to keep it on the hush, OK? I just found out John and Tracey are getting married soon, but I have to keep the news on the hush!
