Hudson, 36, who made an appearance at "The Late Late Show", said the music she writes is really "depressing", reported People magazine.
"No, it would be so fun, but unfortunately the music I write is really depressing. I've been musical since I was young. I've been writing music since I was 18 - even younger," she said.
The "Almost Famous" star revealed that her earliest musical gems that she wrote when she just 11 years old was titled "Why Is He Acting So Stupid?".
