June 14, 2006 - Renée Zellweger has told Nicole Kidman to call off her wedding - with less then two weeks to go. The Bridget Jones' Diary star has reportedly begged her actress friend not to wed fiancé Keith Urban on June 25 because he is a workaholic just like her ex-husband, country music star Kenny Chesney.

A friend of Renée's told Britain's Grazia magazine: "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 is also believed to have reservations about the marriage after his actress daughter - who has two adopted children from her marriage to Tom Cruise - refused to make Keith sign a pre-nuptial agreement.

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

The Moulin Rouge star has invited 80 close friends and family to her nuptials at Sydney's Mary MacKillop Chapel next week, and has arranged for Australian celebrity chef Luke Mangan to cook a wedding breakfast for all the guests.
