"I've dated a couple of the wrong guys, but I've also had great love in my life," the actress tells this Sunday's issue of the Chicago Sun-Times' magazine, SPLASH.
"I think every woman on Earth has dated the wrong guy at some point."
She didn't mention him by name but Bush also dated her OTH costar Austin Nichols on and off for four years after her divorce from Murray.
Now the TV vixen is returning to the small screen in a decidedly different type of role, playing a tough cop in Chicago P.D., premiering January 8.
"It's a new kind of show, Bush says. "Every episode isn't wrapped up in a bow every week. It's not pretty."
But Bush certainly is exactly that. And she showed it off with plenty of sexy attitude in a glamorous photo shoot that she took with SPLASH.
"I'm a strong person and that can translate into a strong personality," she says.
