The couple - who have three-year-old twins, Max and Emme, together - announced their split in July after seven years of marriage but the Latino singer insists Jennifer will forever have a place in his heart.
He said: "I`ll always love Jennifer."
Marc also revealed how neither of them were surprised by the split because they had both come to the conclusion the relationship wasn`t working.
He said: "I`ll tell you that it wasn`t something sensationalistic happening. It was a realisation on both our parts. So, you know, it wasn`t shocking. These things happen. It was a decision that we made jointly."
Marc is now trying to move forward with his life and doesn`t want to dwell too much on the past.
He said in an interview with ABC News` John Quinones: "This is not a funeral. This is not a burial. This is just two people who came together and just realised - and so I`m saying that it wasn`t sustainable the way it was, and that`s that."
Jennifer recently revealed her torment at the divorce as they both wanted the marriage to work.
The `American Idol` judge said: "This was the hardest decision I`ve ever had to face. I really wanted this family to work. That was my biggest dream, and I worked hard at it. We both did. Sometimes it doesn`t work - and that`s sad. But I remain an eternal optimist about love. I believe in love...It`s still my biggest dream."
