Photos of Nicole Richie, Rachel Zoe, Benji Madden, Nicky Hilton at Byron and Tracey Salon Party in LA

Nicole Richie and Rachel Zoe posed together last night while supporting their hairstylist friends, Byron Williams and Tracey Cunningham, at their salon's party in LA. We've seen the girls reunited before, and it looks as if everything is amicable again between the two. Jenny McCarthy enjoyed a drink with Byron while Tori Spelling and Dean McDermott chatted with Lisa Rinna, and once again Nicky Hilton showed off her fab style. At the end of the night Benji Madden took Nicole home after what looked like a fun time for the celebrities celebrating the people that help keep them beautiful.
