Playing the role of proud papa, Joel Madden took baby Harlow to the Farmer’s Market in Los Angeles this afternoon (September 20).

Harlow, who was sitting pretty in her very own little red Radio Flyer wagon, just recently became a big sister when new brother Sparrow was born on September 9.

And while family matriarch Nicole Richie was nowhere to be seen, her influence was abound as evidenced by Harlow’s adorable floral headband.

Meanwhile, it appears Nicole has reportedly revealed that she would like to marry Joel.

A source has been quoted as saying: “Nicole has never been in a rush to get married to Joel. She’s so happy with him and their little family that she didn’t feel the need to change the way things were between them. But when Adam died, she freaked out. She realized life is fragile and short. She doesn’t want to have any regrets at all, and she does want to be Joel’s wife.”
