Leonardo DiCaprio is back at being a bachelor again after several months of being pre-occupied with Kelly Rohrbach, a Sports Illustrated swimsuit model.  The "Revenant" star is enjoying some solo free time as well as doing something good for humanity.

DiCapro has recently been in the news because of his break up with Rohrbach. For a refresher, the 41-year-old Hollywood star seems to have a knack for models. His exes include Bar Refaeli, Erin Heatherton and Toni Garrn. It also seems that he wants some brains to come along with the beauty, with being Earth-friendly also a plus.  He was recently quoted saying, "I could never be with someone who doesn't believe in climate change," to Germany's TV Movie magazine.

"The Wolf of Wall Street" actor's personal mission seems true to the heart. He even set up a foundation that is said to focus on humankind's extended health and well-being, which is called the Leonardo DiCaprio Foundation. He also had the chance to share his views during a speech at the 2014 UN Climate Change Summit, the Belfast Telegraph reported.

In that speech, DiCaprio stated that, "I believe humankind has looked at climate change in that same way: as if it were a fiction, happening to someone else's planet, as if pretending that climate change wasn't real would somehow make it go away."

Meanwhile, DiCaprio took a well-deserved break and celebrated the New Year with friends, before going back on promoting his latest film. The actor hosted a New Year's party in St. Barts, which also had Justin Bieber offering musical entertainment, People Magazine reported.

DiCaprio's "Revenant" is about an American frontier of the 19th century, who was attacked by a bear and was left to die out by his companions.  The movie hit the big screens on Christmas day. This, once again, gave DiCaprio a Golden Globe nomination.
