Cevey, 43, and Collins, 65 -- who were married for nine years before splitting in 2008 -- have two sons together, 14-year-old Nicholas and 11-year-old Matthew. Cevey said the two have remained close through the years, despite Collins having to pay Cevey a record-breaking $46.76 million per the terms of their divorce settlement.
"Love was never completely gone," she said. "[It] was just on another level. We've known each other for 22 years, 15 we were a couple. Now we feel both the same thing: We should never diverge. The separation was a wrong decision."
"We were always very close, because of the children," she added. "But just last year, I realized that he is indeed the man of my life."
Cevey said her second wedding to the GRAMMY-winning musician will be a much smaller affair than their lavish, star-studded wedding at the Beau Rivage Hotel in Lausanne, Switzerland in 1999.
"The important difference is that now our children can be there -- for me the most beautiful change," Cevey said. "And I imagine the next celebration will be more familiar and [smaller]. For our first wedding in 1999 in Lausanne, we had to invite many more people to not disappoint anyone."
Earlier this month, Collins talked to The Insider about rekindling his romance with Cevey, and said that the two were always "very civilized" with one another even after their initial split.
"Obviously, with every separation there's a period where you don't talk to each other,” Collins shared. “Soon, we became great friends again and she used to come to my house. I used to go to hers and have dinner. [Our kids] don’t want mom and dad arguing. … When they went to Miami, I followed and we kept in touch, and we realized that we missed each other and made a mistake. Just decided to do it again."
"You've learned by mistakes," he added. "Both of you are to blame in this. No matter how peaceful you want it, there is a war. You learn how people are. It's working, that's all I can say."
Collins has been married three times. He has two children from his first marriage to Andrea Bertorelli, Simon and Joely Collins, and one daughter from his second marriage to Jill Tavelman, actress Lily Collins.
