NEW YORK, Sept. 23 (UPI) -- Leonardo DiCaprio joined Instagram on Tuesday.
The 39-year-old actor posted his first photos from the U.N. Climate Summit 2014 in New York. DiCaprio was named a U.N. Messenger of Peace last week, and spoke on climate change at the opening ceremony. The star called the event the "perfect setting" to join Instagram, and shared a picture of himself with U.N. Secretary General Ban Ki-Moon.
