“I knew that Alex was designing a ring, but I honestly wasn’t expecting a super elaborate proposal because we already had the wedding date set, but he planned such a beautiful experience for me,” she told the outlet. “I was so surprised!”

Cassie thought she was getting ready for her birthday dinner with her family when she pulled up to meet Fine, who was on location with the Compton Cowboys, a group that uses horseback riding to engage inner-city kids in Compton, California.

She was surprised to find aStevie Wondersong playing, and when she was escorted out back, she saw guys on horses with their initials tied above them. Fine then came around on a horse as well.

“When he got down on one knee, everything just stopped,” she said. “I felt like I lost my sense of hearing; I just saw his mouth moving, and he said ‘I want to spend the rest of my life with you.’ ”

The two enjoyed dinner on the beach complete with a bonfire after. “I will never forget how special Alex made me feel that night,” Cassie said.

The pair wrote their own vows and Cassie walked down the aisle to Kina Grannis’ “Can’t Help Falling in Love.”

“I felt really relaxed during the ceremony,” Cassie said. “As soon as I saw Alex, any nerves that I did have went away, and I just couldn’t stop smiling.”
