As for 37-year-old Ashlee, she slicked her hair back into a sleek ponytail and wore a silver gown covered in feathers.

"Most beautiful wedding 😍 love you," Ashlee commented on the post.
Jessica added, "I’m still crying. You are instep with your purpose and the light that surrounds you is divine. You are the fairy of your fairytale my forever sister 💫💍🙌🏼"
It seemed that Jessica was celebrating some pre-wedding festivities over the weekend, sharing a photo of herself in a tuxedo-inspired black jumpsuit and heels, posing with her husband, Eric Johnson.
