According to The Sun, the couple was declared “wife and wife” by an Elvis Presley impersonator at the Little Vegas Chapel. While it’s unclear when the wedding took place, both women have been spotted wearing matching gold bands on their ring fingers since at least June 5.
The Sun says the brides both wore black with Ashley, 29-years-old, wearing high heels and carrying a bouquet.
After tying the knot, the happy couple posed for their first photos as newlyweds in a pink Cadillac.
The small ceremony was only witnessed by a handful of guests, which The Sun says may have included Charlize Theron, the Jonas Brothers, and Sophie Turner.
Sophie and Joe Jonas also wed in a Vegas ceremony back in May.
The Blast reached out to reps for both Benson and Delevingne but have yet to hear back.
Michael Kelly, who owns the chapel, told the paper, “They were sure about what they are doing and they were sure about what they mean to each other. They were clearly devoted to each other and they had the biggest smiles on their faces."
He added, "You could see that they were serious about what they were doing but having the most fun. They wanted it simple, quiet and easy.”
Delevingne gushed about her partner in a speech at the TrevorLIVE Gala back in June.
“I also have another very special woman in this room to thank and you know who you are,” she told the audience. “She’s one of the people who help me love myself when I needed it most and I really needed it. She showed me what real love is and how to accept it, which is a lot harder than I thought.”
Cara was first linked to Ashley in June of last year.
