Katharine McPheeKatharine McPhee doesn't have any biological children yet, but her four-legged friends keep her busy. The former 'American Idol' runner-up brings her Chihuahuas with her wherever she can take them, much to her husband Nick's bemusement.

"Yeah, sadly, I'm codependent on them," she tells PopEater. "Sometimes [my husband] rolls his eyes when I say, 'The dogs are coming, right?' I finally just overheard him saying to somebody, 'It's a little bit of a security blanket for her,' and I thought, 'He's probably right.'"

But even McPhee, whose new album, 'Unbroken,' came out earlier this month, knows that her furry friends aren't welcome in all quarters.
