Why Has 'Married at First Sight' Expert Dr. Viviana Coles Left the Show?

Married at First Sight is heading to San Diego for Season 15—but one of the Lifetime shows relationship experts will not be making the trip to the west coast.

Dr. Viviana Coles confirmed earlier in June that she would be exiting Married at First Sight after Lifetime unveiled new experts DeVon Franklin and Dr. Pia Holec.

Married at First Sight fans soon began to ask Coles on social media whether she had plans to return to the season, leading her to take to Instagram to explain what was happening.

Here's what she wrote.

On her Instagram, she wrote the following: "I have always stayed busy with meaningful projects in my professional and personal life.

"I have decided to focus more of that energy on new exciting opportunities to further my mission to help others in their intimate relationships.

"I won't be returning to Married at First Sight next season but I am so grateful for my 7 seasons of Unscripted TV Series with Kinetic Content. [sic]

"I believe in the MAFS process and in my colleagues and will continue to wish all of the upcoming participants the best."

She followed this up with a video filmed after she had wrapped her final scenes for the show.

In this, she said: "It's a very emotional day, but I'm so grateful for this opportunity. I'm so grateful to have been a part of this process and to have been a part of bringing couples together in love and teaching individuals on how they can be the best partner to others—what to do and what not to do."

As part of Coles' decision to focus on new opportunities, she is currently on a book tour promoting new book The 4 Intimacy Styles: The Key to Lasting Physical Intimacy.

Rumors started to spread among fans of the show back in March, when spoiler sites started to report that she was exiting the series.

Franklin and Holec will be the ninth and tenth experts on the U.S. version of Married at Fight Sight.

The original line-up consisted of Dr. Joseph Cilona, Dr. Logan Levkoff, Dr. Pepper Schwartz, and Greg Epstein. Schwartz was the only expert carried over to Season 4, when the rest were replaced with Cal Robertson and Rachel DeAlto.

DeAlto was replaced in Season 6 by Dr. Jessica Griffin, who in turn lost her place to Coles in Season 10.

Married at First Sight airs Wednesdays at 8 p.m. ET on Lifetime.
