Keith Urban is said to be determined to star over after his split from Nicole Kidman.

Insiders have revealed that while the country music star is already father to two daughters, Sunday Rose and Faith Margaret, he hopes to expand his family again.

Notably, old rumours surrounding claims that Urban may have fathered a secret child in 1990s have resurfaced online. The source said, "Keith is always quick to deny it but a lot of people think there's more to the story than he's willing to admit," according to Radar Online.

On the other hand, sources revealed that while Kidman and Urban have talked about kids for years, but "they were never able to agree, so now that he's single and free to do what he wants, making that happen is at the top of the list."

This comes as Keith Urban has had limited contact with his daughters since the split from Nicole Kidman. The source said, "It's like he doesn't exist."

Adding, "He's still in damage-protection mode with Nicole and their girls."

Furthermore, Urban is reportedly keeping his plans to expand his family under wraps, but still hopes that "everyone will see [his starting a second family] as a positive thing."

Kidman and Urban tied the knot in 2006 and finalized their divorce last September following allegations that the former Voice judge had wandering eye.
