A mass search is underway for a cruise ship entertainer who mysteriously fell overboard after posting a number of haunting tweets.

Arron Hough, 20 failed to show up to play at the Royal Caribbean Harmony of the Sea's Christmas Day performance of the iconic musical Grease. 

A Hercules aeroplane and Coastguard vessel have been frantically searching for the British national, News.com.au reports. 

Mr Hough was last seen at 4am on Christmas Day, when security cameras captured him on Deck 5 of the vessel. It is believed he fell overboard, although the circumstances surrounding his disappearance are unclear. 

However it's now emerged Mr Hough posted a series of unsettling tweets in the lead-up to his disappearance. 

The social media posts suggest he may have been struggling with life on the vessel.

"Pretending to all of our followers that we're having such an amazing crazy ride when actually we're not," he wrote in one.

"We struggle, we have hard times but we hide this with happy pictures we post ... sometimes you gotta embrace the facts that you're feeling down and you're feeling alone.

"But don't think this is a bad thing, to embrace the positives you also have to acknowledge the negatives."

Another posted a couple of days later reads: "Beneath the water is beauty. Always look beneath the surface before you decide on things".

Mr Hough also complained of sea sickness in the days leading up to his disappearance.

The vessel's officials are yet to confirm if Mr Hough's overfall was captured on camera.

He is described as a much-loved member of the ship's entertainment team.
