According to reports, Nicole Richie has been missing her days as a “party girl.” Sources say the 26-year-old new mom is “torn” between her duties as a mother and partying.

“Nicole is torn between being a mommy and being a party girl,” claims an insider. “She wants to go out and have fun, but when she does, she’s like, ‘Uh-oh,’ Harlow needs me. She really misses her carefree life.”

Richie gave birth to Harlow Winter in January. Harlow is her and boyfriend Joel Madden’s first child. “Before Harlow came along, Nicole never had to worry about anything. All she did was party with her friends and go shopping. Now she’s totally overwhelmed by her new responsibility, even though she adores her daughter,” added the insider. “Nicole still can’t figure out if she’s happier when she’s home with the baby or hitting the town with her friends!”
