Nicole Richie and her former stylist Rachel Zoe have ended their feud.

'The Simple Life' star - who reduced Rachel to tears after calling her nicknames including "raisin face" and "lettuce cup" on her MySpace page - was seen happily speaking to the fashionista at a Los Angeles store opening earlier this week.

She said: Nicole is now what people refer to as the big thing that happened

An onlooker said: "Nicole and Rachel introduced their partners to each other. They talked for 20 minutes about real estate and the economy."

Rachel was little known before her well-publicised war of words with Nicole.

She has since penned a book 'Style A to Zoe: The Art of Fashion, Beauty, and Everything Glamour' and has a TV show on US network Bravo entitled 'The Rachel Zoe Project'.

Rachel, 37, has always insisted it was her collaboration with Nicole which secured the star's position as one of the world's foremost fashion icons.

She said: "Nicole is now what people refer to as the big thing that happened. Everything went from nowhere to everywhere. Nicole was about creating a look.

"Because of her fashion sense, which was really my fashion sense, she became famous. It was a huge moment - Nicole became a style icon without being a star."
