Cut the girl some slack--if you'd been engaged to Marilyn Manson, you'd be a little marriage-shy, too

Rose McGowan and marriage just don't seem to mix.

For the second time in her life, the 36-year-old has backed out of plans to wed.

The actress has called off her engagement to director Robert Rodriguez, Radar Online reports. McGowan previously cancelled her two-year-engagement to rocker Marilyn Manson.

She starred in Rodriguez's 2007 film,"Grindhouse," and has a part in his upcoming movie, "Machete," out in 2010. McGowan's also set to star in the Marvel Comics adaptation of "Red Sonja," which is being produced by Rodriguez, and is due to hit theaters next year.
