Why Keith Urban Is Being ‘Extra Secretive’ About Who He’s Dating Post-Nicole Kidman Split (Exclusive)

Big little boundaries!

Keith Urban has a few strict, non-negotiable rules for anyone he dates following his shocking split from soon-to-be ex-wife Nicole Kidman, a source reveals to Globe.

The “Somebody Like You” singer, 58, “has always been private but now that he’s going through this divorce from Nicole, he’s extra secretive,” says the source. “He wants to sow his oats and enjoy himself, but the last thing he needs is for that to get out.”

To ensure that doesn’t happen, “any woman who goes out with Keith has to sign a very detailed non-disclosure agreement,” spills the source. “He also won’t meet anyone out in public. They have to be willing to come over.”

It’s not just his privacy Urban is worried about. The country star is also a parent — he and Kidman, 58, share two teenage daughters, Sunday Rose, 17, and Faith, 14.

“Keith admits that having these sorts of rules for his love life makes things more complicated, but for now at least, that’s the only way this will work for him,” explains the source. “He wants to keep things as amicable as he can for the sake of the girls.”

And it does seem to be working. The identity of the country star’s new girlfriend has yet to be revealed with reports simply referring to her as a ‘mystery woman.’

“People have just been grasping at straws trying to figure out who he’s been seeing. It’’s been a guessing game,” says Globe’s source. “Keith’s pretty proud of that because it goes to show [that] he’s chosen the right people to surround himself with.”
