According to USA Today,
Leonardo has really signed up for a trip to Mars. On Monday Leo attended President Obama’s South by South Lawn summit and cracked a joke that he has signed up to fly to the red planet. Kathrine Hayhoe was doing her speech on climate change and according to USA Today, she quoted: “As long as we haven’t signed up for the trip to Mars. I don’t want to know if anyone has.” That’s when Leo chimed in saying “I did”. Once the story was released, the internet didn’t hold back with the titanic memes.
We wont let you go Leo haha.
