Nicole Richie is making some big changes in her life. After more than 2 years together, Nicole has fired her stylist Rachel Zoe. Nicole and Rachel are close friends, and Nicole has looked beautiful at many various events over the years but it was time for a change. Nic said she, “wanted to surround herself with positive people and influences." Sounds like she really is into making her life a more healthier one. US Weekly reports:

Apparently that didn’t include the controversial fashionista, 35, who has long been accused of promoting unhealthy body images (her roster of stick-thin clients includes Mischa Barton and Lindsay Lohan, both 20).

“Nicole didn’t trust Rachel anymore,” a Richie pal says of the firing. “Zoe didn’t take the news well.”

Zoe’s rep denies this, adding that the split was amicable.

In her place, Richie has hired Cristina Ehrlich – who has dressed Jessica Biel and Penelope Cruz – to pick an outfit for the November 21 American Music Awards, where the actress has been asked to introduce a performance by dad Lionel Richie.
