Reese Witherspoon looks pretty in pink while walking the carpet at the premiere of her new movie Inherent Vice on Wednesday evening (December 10) at the TCL Chinese Theatre in Hollywood.

Also joining in on the fun were the film’s stars Joaquin Phoenix, Josh Brolin (with girlfriend Kathryn Boyd), Benicio Del Toro, Maya Rudolph, Sam Jaeger, Timothy Simons, Jordan Christian Hearn, Yvette Yates, and others.

Reese‘s daughter Ava, 15, just joined Instagram and one of her first posts got comments from both mom and dad Ryan Phillippe.

“merry minimalist Christmas @ryanphillippe,” Ava captioned the below photo of a tiny snow globe. “a lil excessive…” Ryan commented while Reese wrote, “Very minimal @avaphillippe,” along with a Christmas tree emoji.
