“It’s the nature of it, and we still have each other after all these years,” she added toET. “And I’m just so grateful for them and they are a highlight of my life. Not professionally, but our friendship and our sisterhood — you’re going to make me cry.”

“Titan is in the process of going from our bed to his bed, so he called, ‘Mommy, Mommy!’ And I go there in the middle of the night and next thing I knowI was like, ‘You need to go get your dad,'” the mom of two said.
Now, Rowland is dealing with splitting her time between her two boys, she toldET, as Titan “still needs the attention that he got before Noah” — the latter of whom “has his own set of needs right now.”
“Yesterday, [Titan] dragged me down and was like, ‘Mommy, I need you to look at me. I need you to see me,’ which is what I tell him,” Rowland said. “I was like, ‘If ever Mommy is getting busy or something, you have to tell me. Iwant to give you everything that I can, but if I don’t and you feel like you need something, you have to tell Mommy.’ "
“So he does, and he did,” the singer continued. “And we sat and talked together, so he was very, very happy last night.”
