Kylie Minogue wants her fans to leave her ex-boyfriend alone.
The Australian singer, 38, and 41-year-old French actor Olivier Martinez announced their separation this month after four years together.
"As for the treatment Olivier has received of late, I can only reiterate that he simply does not deserve the kind of harassment or vitriol to which he has been subjected," she wrote in a message posted on her Web site.
The tabloid press had speculated that Martinez was seeing someone else. The two have said the accusations saddened them both.
"For someone whom I have enormous love and respect, and communicate with, it is so grossly unfair: to demonize an honest man. I would ask of you, my fans, to show your support for both Olli and myself as a separation is never easy," she wrote, reports AP.
People magazine's Web site reported on her note Saturday.
Minogue, known for hits such as "Loco-Motion" and "Can't Get You Out of My Head," recently resumed performing after treatment for breast cancer diagnosed in 2005.
Martinez has appeared in "Before Night Falls" and the recently released "Blood and Chocolate."
