The hitmaker said, ‘There’s not really an issue, but I think Hailey still has some things she wants to accomplish as a woman.’

He continued,  ‘And I think she just is not ready yet, and I think that’s OK.’

Justin went on to reveal that the Hailey ‘wants to have a few’ children, while he would want to ‘have as many as Hailey is willing to push out. He joked, ‘I’d love to have myself a little tribe.’

The Peaches singer added, ‘It’s her body and whatever she wants to do.’

In July, Hailey shut down pregnancy rumors after Justin posted a photo of the two on Instagram with the caption: ‘mom and dad.’
