A bearded Leonardo DiCaprio recently completed ALS' Ice Bucket Challenge while he was staying at Lake Athabasca.

DiCaprio was accompanied by four of his friends who also did the challenge.

The generous "The Wolf of Wall Street" star vowed to donate $100,000 to the organization who is currently educating people on Lou Gehrig's disease, while finding cure for the said condition.

DiCaprio then challenged Canadian Prime Minister Stephen Harper to complete the challenge within the next 24 hours.
