A month after giving birth to son Tennessee James, Reese Witherspoon didn’t stay long at a party hosted by Bee Shaffer for the opening of Rag & Bone’s store in LA Friday. The “Legally Blonde” star was spotted hugging Cameron Diaz when the two arrived, but Witherspoon left soon after, while Diaz mingled. Diaz’s makeup artist pal Gucci Westman is married to Rag & Bone designer David Neville. Anna Wintour chatted with Aziz Ansari inside the Svedka-sponsored bash.
