It was a family affair for Reese Witherspoon on Saturday night as she supported her son Deacon Phillippe at his Brother Save Us movie premiere.

The 50-year-old actress was joined by her lookalike daughter Ava, 27, and mom Betty, 78, on the red carpet at the 57th Nashville Film Festival.

She looked younger than her years as she stepped out in a strapless white top and black trousers.

Deacon, 22, looked every inch the rising star as he arrived in a textured brown suit, which he teamed with a see-through brown shirt.

Ava wowed in a slinky, low-cut, beige mini dress with thin, diagonal stripes. She added open-toe white platform heels.

Meanwhile, Betty was a beaming matriarch in a dark grey jacket, colorful Gucci neckerchief, and black skirt.

Witherspoon shares her kids with ex-husband Ryan Phillippe, 52.

The exes split in 2008 after nine years of marriage.

The blonde beauty went on to marry Jim Toth, 56, in 2011, and they welcomed son Tennessee, 14 on September 27, in 2012. The now-exes announced their split in 2023, shortly before their 12-year wedding anniversary.

Deacon graduated from New York University in May, and was cheered on at his graduation ceremony by Phillippe, Ava, Tennessee, and Toth.

At the time, Witherspoon shared an Instagram post to commemorate her son's milestone achievement.

She wrote, 'After four years of hard work, long days, endless papers and classes, working with the greatest teachers and making new friends...

'My wonderful son graduated from @nyutisch! I'm so proud of you @deaconphillippe!'

As he makes his feature film debut, Deacon addressed his nepo baby status in an interview with Variety this week.

'I acknowledge that I'm extremely lucky, but you know, at the same time, I hold myself to a standard. 

'I'm not really looking to prove anything to anyone but myself to try to be the best version I can be, the best person I can be and work as hard as I can,' he told the outlet.

Brother Save Us is set 'on a farm in the dystopian Midwest, where crops are dying as the world crumbles, but an inseparable bond makes life worth living for brothers Cole and Nat,' per Nashville Downtown.

The synopsis notes, 'Cole works hard to fill Nat's days with light and hope – to shield his brother from the harsh truths of their world. But after Pa buys an AI farm bot from the controversial tech company Agentico to ensure they make harvest, everything starts to change.'

Deacon is listed as a producer on the movie, which was directed and written by Jesse Behrenwald.

The project also stars Thomas Murphy Molony, Chandler Riggs, Forrest Weber, Amy Sloan, Kroydell Galima and Victor Holstein.
