Nicole KidmanRenée Zellweger has reportedly warned Nicole Kidman that her marriage to Keith Urban will not be everything she wants it to be and that Nicole should call off the wedding, with less than two weeks to go.

Renée is worried that the marriage will end in tears because Keith Urban is a workaholic like Renée’s ex-husband Kenny Chesney. Renée was married to Kenny for just four months before they filed for annulment.

A friend of Renée’s quoted in Grazia magazine revealed: “She’s been saying to Nicole, ‘You won’t know till your married and it’s too late’.”

“She says Keith has all the signs of being a workaholic and that is dangerous for Nicole and her family.”

Nicole’s father also has doubts about his daughter’s wedding plans because she refuses to make consider a pre-nuptial agreement.

A source has reported: “Her dad is against Nicole getting married without a pre-nup, but her mum thinks she should follow her heart.”
