Leonardo DiCaprio: TAG Heuer Event with Cameron Diaz!

It’s a Gangs of New York reunion!

Leonardo DiCaprio makes his first appearance since his split with girlfriend Erin Heatherton at an event for TAG Heuer on Saturday evening (November 10) in New York City.

The 37-year-old actor helped his former co-star Cameron Diaz celebrate the launch of her limited edition signed watch at the event which raised money for the UN Women and New York Cares’ Hurricane Sandy relief effort.

Leo‘s split from Erin was announced last week, just days before she walked in the Victoria’s Secret Fashion Show.

FYI: Cameron is wearing SLANE bangle bracelets.
