The singer, whose latest record has sold less than half a million copies worldwide, said that its commercial failure was due to "promotional issues" and being forced to finish the record shortly after filming her new movie Burlesque.
"I was really proud of that record. I think there was a lot of promotion issues, coming from a standpoint of how everything resulted," she told Collider.
"I started recording that record before I went in to make the movie and, by the time I ended the movie and came out of it, I had to jump right into that record.
"By the time I was done with the movie, I was just a completely different person, and I had new things to say and new points of view."
The 'Beautiful' star also admitted that she is a "changed woman" since making the LP, and is keen to start work on a new album.
She continued: "Now, I’m in a place where I’m very much in an introspective state of mind, have a lot to say, and have grown leaps and bounds from that film.
"I’m a changed woman. So, I’m very much ready to actually make a new record. Nothing is ever a setback. If anything, it just motivates you for what’s next."
Bionic producer Tricky Stewart recently claimed that Aguilera was "poorly promoted" throughout the album campaign.
