Marc Anthony: 'I'll always love Jennifer'

Singer Marc Anthony is speaking out for the first time about his split from Jennifer Lopez.

In an interview with ABC's "Nightline" set to air on Thursday, Anthony gets candid about his split with Lopez and admits, "I'll always love Jennifer."

Lopez, 42, and Anthony, 42, announced in July that they were breaking up, but they did not specify a reason for the split. The two married in June 2004 and their twin son and daughter, Max and Emme, were born in February 2008.

"I'll always love Jennifer, she knows it ... and my kids know that," Anthony says in a preview clip for the interview, which can be seen below. "Jennifer is a wonderful, wonderful woman. A wonderful mother. A wonderful friend."

When asked about the split, Anthony says, "It is sad because you think about the impact of all those people who believed in you, you think about your family, you think about the possibilities."

He adds, "We realized very, very early on that even though we're not together this story is not over. There's stuff to do together, there's stuff to see together through Max and Emme."

The two were spotted together earlier this month in Southampton, New York, but according to his spokesperson, the recently separated couple got together for their children's sake.

Lopez was the first to comment about the couple's split. She did it in an interview with Vanity Fair's September issue.

"To understand that a person is not good for you, or that that person is not treating you in the right way, or that he is not doing the right thing for himself - if I stay, then I am not doing the right thing for me," she said.

Lopez has been married twice before but has no other children other than her and Anthony's twins. She and Ojani Noa were married between 1997 and 1998. Lopez wed actor and dance choreographer Cris Judd in 2001. They divorced in 2003.

Before Lopez, Anthony was married to actress Dayanara Torres between 2000 and 2004. They have two sons - Cristian, who was born in 2001, and Ryan, born in 2003. Anthony also has a daughter named Ariana, who was born in 1994, with ex-girlfriend Debbie Rosado.

Part of the interview will air on Thursday's "Good Morning America." The full interview will air Thursday night on ABC's "Nightline" at 11:35 pm. See a clip below.
