"I'll tell you that it wasn't something sensationalistic happening," said Anthony in an interview broadcast on Thursday by ABC, breaking the silence he had maintained since news of the divorce broke.
"This is not a funeral. This is not a burial," the 42-year-old singer and actor said of the breakup. "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."
The artists announced their divorce on July 15, but rumors about a possible split had followed them ever since they married, even after the birth of twins Emme and Max three years ago.
Anthony said that Lopez's request for a divorce did not surprise him, and he also denied that he had been unfaithful to her, despite the fact that Us Weekly magazine reported recently that he had had an extramarital affair with a flight attendant in 2009.
Meanwhile, Anthony added that he will "always" love Jennifer, 41.
