Carrie Underwood's life has been a "dream" since she won 'American Idol'

The blonde-haired beauty shared a sweet post of her performing on the competition after being announced as the winner on her Instagram account.

The upload was captioned: "12 years later and I'm still not sure how it all happened to me! 12 years ago today, my dreams came true and life has been a dream ever since! I am beyond blessed and so thankful! #AmericanIdol #TBT (sic)."

And the 'Jesus, Take The Wheel' hitmaker has revealed she would whole-heartedly support her two-year-old son Isaiah - who she has with her husband Mike Fisher - if he wanted to follow in her footsteps and become a musician.

Speaking previously about her child's future, the Oklahoma-born star said: "We're ready to support him in whatever it that he wants to do and be and whoever he wants to become, but I just want him to be happy."

And all Carrie - who recently revealed she is taking a short break from her career to focus on motherhood - wants is for her child to credit her and her spouse as "good parents" when he is older.

She added: "I want him to say, 'I had good parents, I had a good childhood.' And I just want him to do good things in the world."

And Isaiah is already showing his love for performing.

Carrie explained: "He loves to sing, he loves to dance and he loves to just be kind of a show-off. So I laugh all day, every day."
