A Flight Attendant reported their flight had an engine failure and diverted to a nearby airport.

Narrative

Flight began normal; nothing out of the ordinary. In cruise; after service; I heard a noise I did not recognize. The plane moved in a way that did not seem normal from my experience; and then got more quiet than usual. I gathered something was not quite right. I got mentally ready to accept a briefing from the Captain. A few moments later I got the emergency call from the Captain and he's asked if I was ready to copy a briefing. He told me that we had an engine failure and that we would be diverting to ZZZ. He told me to prepare for a normal landing in approximately 20 minutes and asked me to report back when the cabin was ready. He also told me he would advise the passengers which he did. I then also reiterated what the Captain had said to the passengers and prepared the cabin for landing. All passengers remained calm. And we landed normally. Passengers deplaned without further incident. I believe the entire crew handled this potentially very serious situation with great calm and confidence. The entire crew worked well together; we were very competent in handling the plane and passengers. Passengers were happy to be on the ground safely and thanked us as they deplaned.
