Nicole Richie, Joel Madden and baby Harlow are featured in the upcoming June issue of Harper’s Bazaar.

The shoot took place at grandpa Richie’s home in Beverly Hills.

Nicole told Extra! that her whole life has changed since becoming a mother, and she wouldn’t have it any other way. “Everything I do is for her. My whole life revolves around her and I absolutely love it. I was so excited from the minute I found out I was pregnant… and it’s been nothing but an amazing ride since.”

Nicole adds that her friends adore Harlow and that they have all grown up a bit since she’s been in their lives. “I feel like my group of five to ten friends, they really love her, like she’s theirs… my friends never go outside for smoke breaks anymore, they don’t curse, they are definitely more demure. It’s actually been really interesting.”

One thing that might (or might not) surprise you is that daddy Joel does most of the dirty work when it comes to the baby. Nicole admits, “Joel actually changes more diapers than I do. It’s his time with her. He sings to her, he laughs with her, plays with her. It’s amazing.”

She adds, “I’m the luckiest girl alive right now. I have nothing to complain about.”

The magazine hits stands May 20th.
