She told The Cut: “I like feeling good about myself, being rested, and doing an exercise that makes me feel good physically and mentally.”

Julianne takes care of her fair skin and says she never skips SPF or her nightly skincare regime. 

“It’s so boring to say, ‘I always wash my face,’ but I do,” she told the website. “But some people don’t. I put on some eye cream, moisturiser, and put my retainer in and go to bed.”

She’s also in a happy relationship with her husband of 17 years, Bart Freundlich, 50.

They have two children together, Caleb, 22, and Liv, 18.

They tied the knot in 2003, but first met in 1996 after the demise of Julianne’s first marriage to John Gould Rubin.

She starred in Bart’s directorial debut The Myth of Fingerprints and she’s continued to feature in most of his films since.
