It looks like Diane Lane is holding up well post-split.

The gorgeous 48-year-old actress stepped out in L.A. last night a week after she and ex-hubby Josh Brolin announced their divorce.

Lane walked the red carpet with pals Laura Dern and Mary Steenburgen at the opening of Cavalia's Odysseo, the new equestrian and acrobatic show in Burbank.

Dressed casually in dark jeans, black boots and black shirt, the newly single star was all smiles while posing for photos during the girls' night out.

Brolin, 45, was also recently spotted sporting a big smile post-split while leaving his house in L.A.

Glad to see the exes in good spirits.
