Actress Riley Keough has opened up about her low-key wedding to stuntman Ben Smith-Petersen, revealing Dakota Johnson served as one of her bridesmaids and her pet dog had to be cut from the ceremony due to bad behaviour.

Elvis Presley's granddaughter wed Smith-Petersen in front of a small group of family and close friends in Napa, California earlier this month (Feb15) and she has now shared photos from her wedding album with readers of Hello! magazine.

Snaps feature the bride in a long-sleeved lace ivory dress designed by Delphine Manivet, posing with her mother, Lisa Marie Presley, and grandmother, Priscilla Presley, who both wore black outfits.

In the accompanying interview, Keough says of her gown, "I wanted the dress to be simple and long sleeve and made of lace. Delphine made exactly what I wanted. I'm not very flashy, I wanted it to be very simple."

Gushing about her big day, she states, "It was the most beautiful, amazing, fun day and night. It was every single person I love in one place. I didn't want it to end", while her new husband adds, "I'd say it was the best day of my life. I don't want to be cliche, but it was. I wouldn't change anything."

However, the couple did have to make a last-minute change to the nuptials after her French bulldog, Grubs, misbehaved.

Keough, 25, tells the publication, "(He) ended up misbehaving during the wedding rehearsal so we had to tell him he couldn't be the ring dog any more, sadly. He was very naughty."

Fifty Shades of Grey star Johnson was included in her bridal party, while her brother, Ben Keough, was one of the groomsmen and their six-year-old half-sisters, Finley and Harper, were flower girls. The twins are Lisa Marie's children with her fourth husband, guitarist Michael Lockwood. Riley and Ben are her two older children from her first marriage to another musician, Danny Keough.
