The 34-year-old singer said she received a lot of criticism for being single, reported ET online.
"I'm from a small town in the South," Clarkson said. "Everyone thought I was gay because I wasn't married with kids already! And I was like, 'That's kind of insulting to the gay community!' But, especially in this day and age, I had a very high bar.
"I think the biggest thing is just getting married later in life," she continued. "You change so much in your twenties. I mean, (my husband) got married at 21 in his first marriage, and they both went, 'What?!' It can be very hard to grow in the same way. Your 20s are all about growth and giant (mistakes)," Clarkson said.
"I have an awesome life, and I can hold this down on my own. I learned that from my mother. She depended a lot, financially, on a man. I don't depend on him, and he doesn't depend on me. We made our own way in our own right, and I think that''s what really helps too.
