Riley Keough is supposedly smitten with a stuntman.

The 24-year-old actress has a starring role in forthcoming feature Mad Max: Fury Road, and she apparently met her new flame Ben Smith-Peterson on set.

And it is claimed Riley quickly fell head over heels for the daredevil.

“Ben worked as a stuntman alongside Riley on the set of Mad Max: Fury Road,” a source told Just Jared. “They’ve become inseparable.”

Riley has previously been romantically linked to several sexy Hollywood A-listers.

She and actor Alex Pettyfer got engaged just six months after making their relationship public in October 2011, but they split up the following year.

Riley, who is the granddaughter of the late singer Elvis Presley and the daughter of Lisa Marie Presley, is said to have been besotted with Alex when they first began seeing each other, which is similar to what she is purportedly experiencing with stuntman Ben now.

Reports at the time alleged she and Alex couldn’t get enough of each other as their relationship blossomed.

"They have been inseparable since they started dating," a source told Us.

Since ending her romance with Alex, Riley was rumoured to be dating Twilight Saga hunk Robert Pattinson.

But her mother Lisa Marie recently dismissed this speculation as cruel hearsay.

"I don't want to say who she's with or not; I will say who she's not with and that is a complete lie, and the silliest thing I've ever heard, is that she was with Robert Pattinson because her and Kristen Stewart are like best friends," Lisa told Andy Cohen on Watch What Happens Live.

“So that was the craziest rumour that I will put to bed."
