Charlie Sheen is well known for his madcap missions. But the Hollywood hell-raiser still managed to raise a few eyebrows when he turned up in Scotland trying to find the Loch Ness Monster last week. The 47-year-old star spent four days hunting for the mythical creature, rumored to live deep below the water in the loch, reports the Mirror. With a reputation for hard drinking and drugs, locals would have been forgiven for fearing the arrival of the A-list actor, who flew in on his private jet. But he was reportedly on his best behavior during the four-day trip — only stepping out of line once to climb a Nessie sculpture on a roundabout. Historic Aldourie Castle’s general manager Lavinia Turner confirmed Sheen had stayed at the venue with several friends. “All I can say is that Mr. Sheen and his party were perfect guests and thoroughly enjoyed their trip to Scotland and Loch Ness,” she told the British tabloid. “They had a wonderful and relaxing time but unfortunately didn’t see any sign of Nessie, although I’m sure they’ll be back in the future to try again,” she added.
