We don't understand how a smart man could be so stupid!

Amber Heard and Elon Musk went public with their relationship on Instagram over the weekend, and people can't believe the billionaire is getting serious with the volatile actress. The Rum Diaries star and the Tesla founder have been dating for about a year, but have kept their romance under wraps up until this point.

The two are currently on vacation in Australia, and were also photographed holding hands and cuddling while zip lining together. The blonde beauty got involved with the father-of-six shortly after her messy divorce from Johnny Depp, and she certainly has a type.... super rich and powerful!

According to Heard's father, the couple are already thinking long-term, too.

"Amber and Elon are both very serious about each other. She would love to get married. One of the things they want to do is settle down and have a family. They are making plans for that," he told Grazia magazine.

He better figure out how to get to Mars in the event of a breakup, because we saw how well that went for the Pirates of the Caribbean star!
