Leonardo DiCaprio Sets a Good Example

Leonardo DiCaprio is no stranger to the green movement. And now he's got his mom on board too--literally.

At the opening of the Bonhams Flagship Showroom for art Thursday night, "Leo and his mom rode up on their bikes and parked right in front on 57th and Madison," reports the NY Post.

Mother and Son looked at some pieces by Andy Warhol and Banksy before hopping back on their bikes and cruising back downtown.
