Nicole Richie is a "completely dedicated mom" according to Joel Madden. The Good Charlotte rocker - who has an eight-month-old daughter Harlow with the star - is constantly surprised by Nicole's parenting ability.

He said: "Nicole is completely dedicated. I do whatever she tells me to do. I'm cool with that. She's really good with the baby. I'm really good with finances. All of Harlow's education and all that stuff, I already have planned."

Ashlee Simpson threw a "white-trash" themed birthday party. The pregnant singer, who is married to Fall Out Boy rocker Pete Wentz, celebrated turning 24 with a fancy dress bash at her parents' Los Angeles home last weekend.

One guest revealed: "It had a white-trash theme. Ashlee wore Daisy Duke hot-pants and platform flip-flops with a bathing suit and a fake tattoo around her belly."

Nicole Richie wants another baby. The TV star - who gave birth to daughter Harlow eight months ago - has hinted she is ready to extend her family, saying: "If it happens, it happens."

Nicole - the adopted daughter of singer Lionel Richie - and her Good Charlotte rocker fiance Joel Madden have also spoke about Harlow's progress, revealing she has already started forming her first words.

Nicole Richie is reportedly furious over her fiance's friendship with Mary-Kate Olsen.

The 26-year-old socialite is believed to have told Good Charlotte rocker Joel Madden, 29, to stay away from the actress after she was seen flirting with him at a recent dinner.
