Leonardo DiCaprio and Erin Heatherton Pictures on Bikes

Leonardo DiCaprio and Erin Heatherton mixed love and exercise yesterday while on a bike ride in NYC. The couple has been hanging out in the Big Apple for the last week, enjoying cycling sessions and meals together at places like the restaurant Candela Candela. Leo and Erin checked out the musical Once as well, after the stage version of the 2006 movie picked up a slew of statues at last weekend's Tony Awards. Leo's on a break from making movies, after wrapping up work on Django Unchained and before starting up on Martin Scorsese's The Wolf of Wall Street.

Erin seems to have taken a page from Leo's book and has taken up acting, too — she recently filmed a small part in Adam Sandler's Grown Ups 2. She and Leo also share a passion for philanthropy. Erin's involved in the charity, The Global Poverty Project, and recently wrote about her involvement. Of discovering the organization, which aims to help those living in extreme poverty, Erin wrote, "In my heart I felt I found that missing link in my life, a way I could use my voice to make a difference in the world . . . I'm only 23, and while every day brings a new challenge, a new lesson and a new self-discovery, I now know that I'm on the right path. I know that I can make a difference in the world." She wrote the article for the Chicago Sun-Times, the biggest local paper for the Skokie, IL native.
