Charlie Sheen is convinced the Loch Ness Monster exists and once tried to find it

Charlie Sheen has expressed a belief that the Loch Ness Monster exists and we're not sure whether that helps or hinders the believers out there.

The unlikely follower of Scotland's mythical creature was so sure that he once even travelled to the Highlands to try and hunt down Nessie himself.

Though there have been numerous sightings over the years, the Hollywood actor decided to take matters into his own hands and see if he could spot the long-necked monster - and he did so in true Charlie Sheen fashion.

The Two and a Half Men star travelled to Scotland in 2013 with his pals, Todd Zeile and Brian Peck.

And since he was 'in the country for starters', he spent an evening on a small boat out in Loch Ness, near Inverness, with their 'gear' - aka a leg of lamb, a big hook and a bottle of whisky.

Willie Cameron - who is a leading figure in Loch Ness tourism - was enlisted to help the trio in their expedition.

One day while going about his business, he received a call from an American who asked him to assemble 'an old-style wooden rowing boat, a traditional Tilley lamp, a boat hook, a thick chain... and a leg of lamb'.

And lo and behold, that American was from Sheen's management team.

Willie told The Daily Record: "I did not know it was Sheen until the day before he arrived."

When it all came together, the 57-year-old actor revealed the news of his plans on Twitter, sharing a photo of himself wearing a metal helmet and his pal Peck, who looks rather confused.

Alongside the snap, he wrote: "MIT grant sanctioned archeologists Pekk & Sheen rig battle gear for tonight's sortie on the Loch Ness. [sic]"

Never a dull moment, eh?

Hundreds of people commented on the tweet, with many supporting his venture - and yes, there were plenty of 'winning' jokes.

"Have fun, play safe. Great hat," said one, while another wrote, "Winning! Handsome fella."

A third quipped, "Hope they don't scare Nessie," with a fourth adding, "You look prepared for tonight's sortie, god speed."

Despite the show of support, unfortunately the hunt didn't prove a success.

Speaking to chat show host Jay Leno in 2014, the actor explained that they had originally wanted to go on the expedition a few years prior, but they had to ditch the plans due to bad weather.

"We wanted to spend one night on Loch Ness with a bottle of whisky and a flashlight, but the weather was so bad that we couldn’t do it," he said.

"But I went back and finally spent that night with a bottle of whisky in a rowboat on Loch Ness."

Although he didn't see Nessie, he did claim that there was an unusual event which unfolded on his last day in Scotland.

He said: "Something happened - there was an event at the top of the water that was crazy."

Then again, that could've been the whiskey.
