Nicole Richie and Rachel Zoe: So Happy Together!

After a hopeful reunion two months ago, it appears Nicole Richie and Rachel Zoe are back to being close pals.

Richie, 27, showed up last night at the Beverly Hills opening of Byron & Tracey Salon, hosted by stylist and reality star Zoe.

“Rachel and Nicole were chatting it up and so excited to see each other,” an onlooker tells Celebuzz. “They were toasting, laughing, hugging and posing together.”

Yet there’s more—the reconciliation may be televised.

Zoe brought along a full camera crew, currently filming the second season of her Bravo reality hit The Rachel Zoe Project.

In addition to the drinking and shmoozing, you’ll catch both fashion faves’ leading men, Joel Madden and Roger Berman.

Zoe, largely credited with turning Richie into a red carpet icon after Nicole broke out on The Simple Life, fell out with Richie in late 2006. Reports said the pair were trading barbs over eating disorders, with some choice words even posted on Richie’s MySpace page.

The two rekindled two months ago, again in Beverly Hills, at the flagship boutique opening of Alberta Ferretti.

Also at Byron & Tracey Salon: Jenny McCarthy, Rose McGowan, Nicky Hilton and a newly single Debbie Matenopoulos.
