NASHVILLE, TN  [Thursday Dec.29.2005]  /Mix103FM.com/ -- On the Keith Urban-Nicole Kidman, apparently Urban's ex-fiancee has been watching and listening and predicts the couple won't marry.

Laura Sigler dated Urban for eight years. They first broke up just before Keith made his first Capitol Records album. Then re-united for a short time until splitting in 2002.

Sigler believes the former, self-described substance abuser will not commit to a longterm relationship with the Hollywood superstar, despite their reported engagement over the US Thanksgiving weekend.

Says Sigler, "Nicole and Keith might date for a while, but it won't last very long. I don't know her but I know him very well." Sour grapes or prophecy? Only time will tell.

Sigler, 35, has not seen Urban since they split.
