Elvis Presley’s eldest granddaughter, Riley Keough, married her Australian stuntman fiancé Ben Smith-Petersen in a “beautiful and intimate” ceremony at a vineyard in California’s Napa Valley on Wednesday (Feb. 4), Hello! can exclusively confirm.

“Riley and Ben were married in a small, private afternoon ceremony surrounded by close family and other loved ones,” Riley’s rep told Hello!. “It was a beautiful day and they couldn’t be happier.”

The star-studded guest list included a who’s who of Hollywood “it girls,” including Kristen Stewart, Zoe Kravitz, and Cara Delevingne.

Riley, who is the daughter of singer Lisa Marie Presley, met her new husband on the set of Mad Max: Fury Road in 2012, but they didn’t begin dating until the beginning of 2014.

The two announced their engagement on Facebook in August, with Ben posting a sweet snap of the happy couple, captioning it: “That just happened…”

It’s the first marriage for the pair, though Riley, 25, was previously engaged to her Magic Mike costar Alex Pettyfer.

Late last year, the flame-haired beauty revealed that the pair are inseparable. “We just went to Australia”, she told Hello! at the time, before adding: “I love it there.”

The newlyweds are also ‘parents’ to a one-year-old French bulldog called Grubs Smith-Peterson, and Riley fondly called the pair of them on set “my boys.”

Riley is close friends with Twilight star Kristen – the pair met on the set of The Runaways in 2010– and has also starred alongside Channing Tatum in Magic Mike, and Juno Temple in Jack and Diane.

On the set of the upcoming film, Mad Max: Fury Road, Riley revealed: “I got to work with really great friends and we had a really great time.” She also added that she “became good friends” with Rosie Huntington-Whitely on the set.

Mad Max: Fury Road hits theatres on May 15, 2015.
