Pop star Anastacia has filed for divorce from her husband of three years, Wayne Newton, according to US website RadarOnline.com.
Anastacia and Wayne, who previously worked as her bodyguard, married in an intimate ceremony in Mexico in 2007.
But the pair separated in January, and Anastacia has cited irreconcilable differences as the reason for their split.
The couple, who have no children together, signed a prenuptial agreement at the time of their marriage.
