The 27-year-old country singer, who married Mike Fisher in June, said the gossip has persisted ever since they tied the knot.
'As soon as you get married that happens,' she told Detroit radio station WYCD.
She revealed that one man even asked her if she had just given birth. She hit back, 'You do not ever ask a woman if she just had a baby. Do I look like I just had a baby?' He got in trouble, and I took his drink away.'
But she did admit that they hope to have children in the not-too-distant future.
She added, 'I know it's possible to be a great mother and to be on the road. You don't have to sacrifice that much. I see people like Martina [McBride] do it, and Faith [Hill] do it. I know it's a possibility. I just maybe need to sit down with them and say, 'How do you do it?''
