Kylie Minogue friends 'worried of heartbreak over Martinez baby news'
Martinez - who dated Minogue for five years until 2007 - announced that he is expecting a child with current partner Halle Berry last week.
Sources close to the Australian singer have stated that she may find the news hard to handle, especially as she has revealed hopes of starting her own family.
"Kylie knows her biological clock is ticking," a friend told the Daily Mail. "Although she'll be happy for Olivier, she'll be very sad for herself."
Kylie Minogue is currently dating Spanish model Andres Velencoso, and the insider added that he is not ready to settle down.

"She loves Andres, but he's almost ten years younger than her. He's not quite ready and she knows it might be too late to bec! ome a mother. It's heartbreaking."
Last year, Minogue congratulated Berry and Martinez after they announced their engagement on Twitter.
Olivier Martinez also took Berry to watch Minogue perform at her sell-out concert in Los Angeles in May 2011.
Kylie Minogue is currently working with producers Stargate on her new album.
