Where in the world is Leonardo DiCaprio?

Naomi Campbell is honored with an IREO Diamond Award at the United Nations on May 2.

Supermodels, a billionheiress, a music executive and...a movie star? They are not the cast of the new Gilligan's Island. They are among the attendees (and one non-attendee) at last night's International Renewable Energy Organization (IREO) Diamond Awards for Renewable Energy presented by Paolo Zampolli and The Friends of Climate Change at the United Nations in New York.

I would like to thank Kahraman Halisçelik of Kanalturk (a news organization from Turkey) for inviting me to this ceremony. I met Kahraman earlier this week at the International Filmmaker Press Meet & Greet at the Tribeca Film Festival. I was intrigued by this event for several reasons. First, I am always interested in learning about ways to sustain our environment through renewable resources. Second, I had never been to the U.N. before. And third, the invitation mentioned that Leonardo DiCaprio would be amongst the guests. Alas, Leonardo did not make it to the reception. Low and behold this morning, I finally found Leo down at the Tribeca Film Festival Family Street Fair, though it was only a realistic looking wax sculpture of the actor courtesy of Madam Tussauds.

Supermodels and Goodwill Ambassadors Naomi Campbell and Petra Nemcova were among the honorees at last night's awards, along with Roc-A-Fella Records Co-Founder Damon Dash. Also spotted was Ivanka Trump.

As I was leaving the event last night, I met Jeffrey Rodman, owner of the Water Street Restaurant in Brooklyn's DUMBO neighborhood. Jeffrey mentioned to me that his restaurant had been rented out during the shoot of the environmental documentary The 11th Hour, which DiCaprio narrates.
