According to E! News, the jewelers who helped create Rimes' ring responded to Rimes' Instagram post, by sharing a post of their own, which read, "Wishing you and your family a very merry Christmas. It was such a pleasure working with you to bring your ring to life. It looks perfect on you."

A short time later, Rimes returned to Instagram, where she shared a photo of herself and Cibrian, along with the caption, "Happy Christmas Eve! #cubanfeast #thecibs #christmaseve #christmasweek #christmas2015 #happy #love #grateful."

Rimes and Cibrian began dating in 2009, when they met on the set of Lifetime's Northern Lights. Although the two were both married at the time, Rimes to Dean Shermet and Cibrian to Brandi Glanville, they eventually filed for divorce and were married in April 2011.

Since their relationship began, Rimes and Cibrian have been frequently targeted publicly by Glanville, but in recent months, their co-parenting relationship with Mason and Jake appears to have grown more civil.
