Nicole Richie is convinced her baby daughter Harlow has not only changed her life, but has been a positive influence on her friends too. The star gave birth to her first child with fiancé Joel Madden in January and insists she has become a better person now she is a mother.

However, Richie - whose friends include socialite Paris Hilton and actress Lindsay Lohan - believes her daughter has also changed the attitudes of her closest pals.

She tells TV show Extra, "I feel like my group of five to 10 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."
