Boyd, 28, showed off her slim physique and toned abs in a burgundy two-piece ensemble that bared her midriff.

Despite the brisk weather, Brolin's former assistant wore a form-fitting pencil skirt with thigh high slit, which she paired with strappy nude heels.

Her silky blonde locks were left down in a straight style and she went with minimal accessories, while allowing the ensemble to take centre stage.

The son of James Brolin made a guest appearance to promote his flick on The Tonight Show with Jimmy Fallon Tuesday night.

Josh has been sporting a signature mustache but the SNL alum and late night host accused the No Country for Old Men actor of growing a 'porn-stache.'

Fallon challenged the SAG Award-winner to shave it off during the live on-air broadcast, to which Brolin accepted after Jimmy teased him for a while.

Giggling and laughing as he slapped shaving cream over the star's features, Jimmy joked: 'This is so awesome right now, this is like a fantasy camera or something...like, "You get to shave with Josh Brolin!" It's like so fun.'
