New daddy Joel Madden may be fond of his girlfriend and baby mama, Nicole Richie, but lil Harlow is the love of his life.

The Good Charlotte front-man made that clear at a Queens College concert yesterday.

According to People, the rocker said:

You know, no matter how many beautiful girls there are in this audience, I must confess that three months ago, I had a little baby girl, and she's my one and only true love."

Is your true love your better half or your mini me?
