Nicole Richie introduced her father Lionel Richie to the stage during the 2006 American Musical Awards at the Shrine Auditorium in Los Angeles.

Nicole Richie, daughter of U.S. singer Lionel Richie, has reportedly fired her personal stylist over concerns about trust.

The 25-year-old co-star of "The Simple Life" has ended Rachel Zoe's 2-year tenure as her personal stylist, and one source claimed that trust was behind the controversial fashion guide's dismissal, Us Weekly reported.

"Nicole didn't trust Rachel anymore," said a friend of Richie's of last Tuesday's firing. "Zoe didn't take the news well."

A representative for the stylist, whose fashion efforts have focused on size-zero actresses Mischa Barton and Lindsay Lohan, has claimed that the split of the former confidantes was amicable.

Us Weekly said that to fill the 35-year-old's fashionable spot, Richie has hired actress Jessica Biel's stylist, Cristina Ehrlich, to find her an outfit for the upcoming American Music Awards.
