Leonardo DiCaprio and Nina Agdal were spotted out on a cute date at the Griffith Observatory in LA on Monday afternoon. Despite the museum being closed, the pair enjoyed each other's company as they took in the beautiful scenery and Leo snapped photos of his model girlfriend. While it's been a little over a month since we last saw the couple, Leo made headlines last week after it was revealed that he signed up for a trip to Mars. During a conversation with Barack Obama and scientist Katharine Hayhoe at the White House's South by South Lawn festival in Washington DC, the actor casually announced that he'd signed up for a trip to the red planet. While it may have been a joke, the $200,000 Elon Musk-crafted trip to Mars seems right up Leo's alley.
