7Confessions: Nicole Richie Struggle Between a Career & Motherhood

Nicole Richie has confessed the birth of her first daughter Harlow changed her life and she couldn’t be happier. But it’s only normal to have ambitions to get back in the game.
Nicole was spotted leaving an audition in Toluca Lake, Calif., on April 11, clutching a script. She explained to an onlooker that she was simply "getting back to work"; however, friends of the star are surprised that Nicole, 26, would be willing to jump-start her career again. "Nicole is thrilled with the way things are in her life, and she couldn't be happier," one of her friends says.
While her fiance, Joel Madden is on the road with his band, Good Charlotte, the pair keeps in touch via iPhone. "While he's away, Nicole is always sending Joel pictures of little Harlow," the friend says. "Joel responds by calling back and singing little lullabies into the phone, which always makes Harlow giggle and smile."
The absence of daddy Joel is hard on Nicole, a source said “Nicole would be happier if he [Joel] just focused on his clothing line. His music takes him away from her and it’s difficult for her to be watching the baby alone while he’s out touring. Nicole doesn’t have a full-time nanny, so she’s watching the baby around the clock and it has taken a toll.”
