Reese Witherspoon and Laura Dern show their longtime off-screen friendship with masked LA stroll

They have been colleagues for years.

And Reese Witherspoon and Laura Dern showed this week that they are off-screen friends as well when they were glimpsed out in Los Angeles.

Reese, 44, and Laura, 53, threw on their leggings and masks and stepped out to take some exercise with a brisk stroll this week.

Laura threw a sleek black leather jacket over a white T-shirt, wrapping another shirt around her waist in case temperatures dropped.

Meanwhile Reese swept her blonde hair into a bun and slipped into a charcoal tank top that perfectly complemented her black leggings.

The dynamic duo first acted together in the 2014 drama Wild where Laura portrayed Reese’s mother despite less than a decade of age difference.

Jean-Marc Vallee of Dallas Buyers Club fame directed the movie which earned Oscar nominations for both Reese and Laura.

The film was adapted from a memoir by Cheryl Strayed and had a screenplay by Nick Hornby who wrote such novels as High Fidelity and About A Boy. 

In December of 2014 they reunited for the New York Times comedy short 9 Kisses with a cast that included the late Chadwick Boseman.

A few years later Laura told New York Times that before she and Reese were friends she had ‘pined to know her because of Southern family and Southern mothers.’

Reese was born in New Orleans and raised in Tennessee, and while Laura was born in Los Angeles her actress mother Diane Ladd is from Mississippi.

‘Nobody makes me laugh harder than Laura. She can put me on the floor with a text message,’ Reese dished in the same New York Times interview.

She cracked: ‘Your next article should be about how our mothers met. They watched Wild together in a theater holding hands.’ 

Laura and Reese reunited with Jean-Marc for the 2017 HBO show Big Little Lies which was based on a 2014 novel by Liane Moriarty.

Reese was also one of the producers on the series along with co-star Nicole Kidman who won an Emmy for her performance.

David E. Kelley, who created Ally McBeal and is married to Michelle Pfeiffer, adapted the TV show from Liane’s novel. 

Although the project was initially meant to be a mini-series it got such an enthusiastic response that it was renewed for a second season.

The first season had blown through the plotline of Liane’s novel but she was prevailed upon to come up with a storyline for season two.

Season two added Meryl Streep to the cast, which has included names like Zoe Kravitz, Shailene Woodley and Alexander Skarsgard since the beginning. 

Nicole teased a potential third season in Marie Claire Australia last month, dishing: ‘David and Liane have a really good idea for it. Watch this space!’

She had dished earlier: ‘Reese and I talk or text once a week. She’s just moved back to Nashville and we’re really close.’

Nicole added in the magazine: ‘We all just want to work together again. I texted Zoë and Laura and they’re in.’

Reese became an Oscar-winner playing June Carter in the 2005 Johnny Cash biopic Walk The Line starring Joaquin Phoenix.

This year Laura joined her ranks by winning best supporting actress for her turn as a glamorous divorce lawyer in the Noah Baumbach film Marriage Story.
