The blonde beauty - who has a nine-year-old son, Evan, from her relationship with John Mallory Asher - told 'Access Hollywood': "It's tough to find a man's man. I'm from Chicago. I'm from the South Side, where guys eat meat and potatoes. They don't know what a vegetarian means. They're a guy through and through. Out here, they want to borrow my makeup and concealer. I want to bring a little bit of importing into my life hopefully, and look for guys outside of LA.
"I don't care if they have a big nose. I don't care if they're bald. Just really sweet and who's a perfect reflection of who I am now," she explained. "They have to have a job. I'd like them to at least be able to buy dinners and stuff like that. That is important."
