Usher Raymond sat down with media mogul Oprah Winfrey on "Oprah's Next Chapter" on Sunday, Sept. 16.

Winfrey flew to Atlanta to chat with the "Yeah!" singer about his bitter three-year custody battle, rumored affairs and the death of his stepson Kile Glover.

Usher opened the episode stating that Winfrey's interview will be the only time he will discuss the custody battle. Usher was awarded primary custody of his two sons, Usher V., age 4, and Naviyd, age 3 on Aug. 12.

"This will be the only time that I've ever chosen to speak about it. I've been a man of integrity throughout the entire process, which I hope my boys will understand."

Usher delved right in on his disappointment with Tameka during the custody battle and why he cried in the courtroom.

"I really felt like we were friends. She made us enemies in a way that I could never understood. It wasn't until I was on the stand, where I cried, when I realized, 'Oh, this is an attack.'"

The "Nice & Slow" singer revealed he wasn't ready to get married in 2001 but wanted to "take responsibility" because he was in love and Tameka was five months pregnant with their first son at the time.

"I wanted to give her the wedding that she wanted. But I wasn't quite ready... I impregnated this woman, we were in a relationship, we were in love. . . I was taking responsibility."

Usher also admitted he wasn't faithful during their marriage:

"Towards the end of our marriage I found myself lost, and I just wanted out, No. I was faithful at heart, but not faithful all the way. Even having a conversation with another woman, period, about matters of your relationship or emotions is, in my opinion, not being faithful.

"But were you involved with another woman sexually?" Winfrey asked.

"When we were separated, yes, I was. We were not divorced."

Usher revealed he was in California when he received a call from Tameka about the tragic ski accident that led to his stepson Kile Glover's death. Usher wasn't sure how "real" it was due to the bitter custody battle so he reached out to Kile's biological father Ryan Glover.

As for how he feels about the loss, he admitted he missed Kile a great deal.

"We cooked together, we laughed, we played, we sang... He loved to sing, he loved to dance, He loved to tell jokes..."

When Winfrey asked him if it was true he did not attend Glover's funeral, Raymond expressed discontent at the rumors.

"It hurts me to hear people speculating that I wasn't at the funeral. I absolutely was at the funeral. I was at the burial as well."

Winfrey asked Usher if he "makes love" to his own songs. "Some may say this would be rather narcissistic, but, uh, yeah," he admits.

"If I were you, I would!!" Winfrey replied.

In 2008, Usher signed a young, unknown talent from Canada. Now, just four years later, the artist -Justin Bieber- is a global phenomenon. Watch as Usher tells Oprah why he was impressed by Justin's passion, talent and potential.
