"I'll tell you that it wasn't something sensationalistic happening," Anthony said in the interview.

Tabloids have claimed Anthony was unfaithful, which he denies. The singer also said the decision was mutual.

"It was a realization on both our parts. So you know it wasn't shocking. These things happen," he said. "It was a decision that we made jointly."

The pair announced their split in July after seven years of marriage. The couple has 3-year-old twins named Max and Emme.

Anthony said he wants to move forward with his life and career. He summarizes his situation as "not a funeral, not a burial."

"This is just two people who came together and just realized - and so I'm saying that it wasn't sustainable the way it was, and that's that," he added.

Part of the interview aired on Thursday's "Good Morning America." The full interview will air  on ABC's "Nightline."
