Olivia Wilde reflected on her days on teen drama The OC on Sunday as she remembered the first time she met her co-star Mischa Barton.

The actress and director, 39, appeared on the hit series in 2004 as queer character Alex Kelly who dated Mischa’s character Marissa Cooper.

Olivia took to Instagram to celebrate The OC’s 20th anniversary, reflecting back on her time when she shared the screen with Mischa and her first impression of her.

She wrote on her story, “Mischa = one of the most beautiful faces I have ever seen. I remember being like WHOOOAAAA.”

Olivia also joked about her character Alex’s butterfly tattoo, which she described as “the s***,” even though it “moved up and down an average of three inches in each scene.”

This isn’t the first time Olivia has reflected on her time on The OC and talked about working with Mischa.

In 2016, the Cowboys & Aliens actress talked about her role during an interview on The Howard Stern Show.

Olivia said she was joking told the casting team that she “didn’t take the job unless (she) was allowed to make out with Mischa Barton.”

And they blanched, and they were like, “Did someone leak the scripts to you?” And I was like, “No way?! I’m making out with Mischa Barton.”‘

Olivia added that it was “so sweet” and not awkward at all between the pair.

The director was one of several previously unknown young cast members, including Amber Heard, Chris Pratt, Shailene Woodley, Max Greenfield, who have enjoyed hugely successful careers as a result of the series’ enduring popularity.

It comes after Olivia showed off her toned body as she soaked up the summer sun in a slew of photos she shared to her Instagram stories on Friday.

The Don’t Worry Darling star, who recently declared her support for the current SAG-AFTRA strike, has been spending time on a scenic beach amidst a tropical getaway.
