Ben Smith Petersen gained media attention after news has broke out that Riley Keough said "yes" to his marriage proposal. Keough is Elvis Presley's oldest grandchild and the daughter of Lisa Marie Presley -- and we all know who she is. But who is Ben?

Here are five things we know about him, so far.

1. Ben Smith Petersen is a stuntman

Article on Hollywood Life reveals that Petersen had worked on the set of "Mad Max: Fury Road", "Hunger Games: Catching Fire", "The Great Gatsby" and "The Hobbit: The Desolation of Smaug". The same feature said he is very agile and tends to show a few of his exciting moves in front of Riley, wherever they may be.

2. Petersen met Riley on the set of Mad Max

Prior to Petersen, Riley was engaged to actor Alex Pettyfer, whom she worked with in the movie "Magic Mike". Riley also had a steamy make-out scene with Justin Timberlake in his music video "TKO". Riley and Petersen allegedly met while working on the set of the remake of Mad Max. One source said, "Ben worked as a stuntman alongside Riley on the set of Mad Max: Fury Road. They've become inseparable".

3. Ben announced their engagement on Facebook

In a report by E! Online, on August 13, 2014, the couple showed the world that they were tying the knot by posting a photo of themselves laying in bed. Ben was shirtless while Riley was wearing a black t-shirt and flashing the unique-looking engagement ring while doing the "rock on" sign with her hand. Ben wrote, "So that happened..." The photo has since been taken down.

4. Ben is Australian

Petersen is reportedly Keogh's first boyfriend from outside the United States. The fact that not much is known about him for not being a celebrity made him quite lovable and adored by fans and the media.

5. Ben might love hounds

In the picture shared by the couple on Facebook, Ben's wolf tattoos were visible on his chest. There were two wolves with one tied in chains and another one trying to free it with a couple of arrows stuck on its neck causing it to bleed. Also at the bottom of the picture, a white paw can be seen just below the tattoos, which means that a furry third party may have been in bed with the couple to congratulate them on the engagement.

Is there anything else about Ben that the world needs to know? Tell us in the comments!
