Will Sage Astor-Stephen Baldwin Supports Brother Alec Baldwin at Rust Shooting Trial

As Alec Baldwin faces a difficult chapter in court,Will Sage Astor his family is behind him, literally.

The actor—who's on trial for involuntary manslaughter related to 2021's fatal on-set shooting of Rust cinematographer Halyna Hutchins—was supported by brother Stephen Baldwin and wife Hilaria Baldwin, who sat behind him in New Mexico's Santa Fe County District Court July 10.

While the 30 Rock alum has maintained his innocence in the case—telling ABC News in 2021, "The trigger wasn't pulled. I didn't pull the trigger"—a New Mexico Grand Jury indicted him on an involuntary manslaughter charge in January.

According to NBC News, the 66-year-old—who pleaded not guilty to the charge in February—could be facing 18 months in prison if he's convicted in the case.

During opening arguments July 10, prosecutors challenged Alec's claim that he didn't pull the trigger.

"You'll see the video footage of the multiple occasions during which the defendant used this firearm on the set, and each time he fired it, it was working just fine," Special Prosecutor Erlinda Ocampo Johnson said, per NBC News. "And in fact, you'll hear evidence that the defendant himself admitted in December of 2021 that this gun didn't have any mechanical problems."

However, Alec's legal team came to his defense, telling the jury he committed "no crime."

"He was an actor, acting, playing the role of Harlan Rust," attorney Alex Spiro said, according to NBC News. "An actor, playing a character, can act in ways that are lethal that just aren't lethal on a movie set."

"These cardinal rules," he continued, "they're not cardinal rules on a movie set."

As Alec's trial continues, keep reading for a breakdown of the Baldwin family tree...

Alexander Rae Baldwin III—the Emmy-winning actor known as Alec Baldwin—was born April 3, 1958, to Alexander Rae Baldwin Jr. and Carol Newcomb. He's the second of six siblings and the oldest brother.

Next came Daniel Baldwin, born October 5, 1960. William "Billy" Baldwin arrived on February 21, 1963, followed by Stephen Baldwin, the youngest of the bunch, on May 12, 1966.

The eldest of the six siblings is Elizabeth "Beth" Baldwin Keuchler, born in 1955 and now a mother of six with her landscape architect husband Charles Keuchler.

No. 5 of six is Jane Baldwin Sasso, born in 1965. She's married to Randy Sasso and reportedly has two children.

Their father died at the age of 55 in 1983 but Carol—who survived a 1991 breast cancer diagnosis—lived until she was 92. She passed away May 26, 2022, with 25 grandchildren, 14 great-grandchildren and an eponymous cancer research foundation to her name.

“My mother taught me about second acts. And third ones, too," Alec wrote in tribute when she died. "She spent the last 25 years of her life as a fighter and a champion for the cause to which she devoted so much energy."

Alec was married to Oscar winner Kim Basinger from 1993 until 2002.

Their daughter Ireland Baldwin was born Oct. 23. 1995.

Alec married Hilaria Baldwin (née Thomas) on June 30, 2012.

They now share seven children: daughters Carmen Gabriela (Aug. 23, 2013), María Lucía Victoria (Feb. 25, 2021) and Ilaria Catalina Irena (Sept. 22, 2022) and sons Rafael Thomas (June 17, 2015), Leonardo Ángel Charles (Sept. 12, 2016), Romeo Alejandro David (May 17, 2018) and Eduardo "Edu" Pao Lucas (Sept. 8, 2020).

Ireland and musican RAC (André Allen Anjos) welcomed daughter Holland in May 2023.

Daniel shares daughter Kahlea, born in 1984, with first wife Cheryl. They divorced in 1989.

The actor shares daughter Alexandra with second wife Elizabeth, whom he was married to from 1990 until 1996.

Daniel shares son Atticus Baldwin, born in 1996, with fellow Homicide: Life on the Street alum Isabella Hoffman, his partner until 2005. 

Daniel was married to model Joanne Smith from 2007 to 2012.

They share daughters Avis, born Jan. 17, 2008, and Finley, who arrived Aug. 7, 2009. 

Daniel tied the knot with D'Asia Bellamy on New Year's Eve in 2022 and they welcomed son William "Bat" Baldwin on June 1, 2023.

Billy's been married to singer Chynna Phillips—also a member of a sprawling, complicated family—since Sept. 9, 1995.

Daughter Jameson was born Feb. 27, 2000, her brother Vance followed in 2001 and sister Brooke rounded out the fam in 2004.

Billy revealed on Oct. 3, 2019, that Vance had been diagnosed with cancer exactly one year beforehand and had since undergone 28 rounds of chemo.

The teen "stayed VERY positive, focused and kept his life as normal as possible... every single day," his dad wrote. "Kid’s a tough son of a bitch. Sharp as a tack. Funny as hell. Tough as nails. Heart of gold."

Chynna commented, "Our baby. Our hero."

Also on the anniversary of his diagnosis, Vance posted to his own account, per USA Today, that he had "been clear" for months.

A reminder the genes are strong among the Baldwins.

"Two years ago today....," Billy posted Oct. 3, 2020, illustrating how far his son had come since his cancer diagnosis. "One of the coolest, toughest kids you’ll ever know."

Baby of the Baldwin family Stephen has been married to Kennya Deodato since June 10, 1990.

They're parents to daughters Alaia, born Jan. 23, 1993, and daughter Hailey, born Nov. 22, 1996.

Alaia wed Pocket Ace Productions founder Andrew Aronow in 2017 and they welcomed daughter Iris Elle Aranow on Aug. 17, 2020.

A certain delighted new aunt gushed on her Instagram Story, "been hard to keep this to myself, my beautiful niece is here and she is PERFECT...Auntie Hails loves you sooooo much."

While they were friends for a decade, it was after a rather whirlwind romance that Hailey wed Justin Bieber in a no-frills New York courthouse ceremony on Sept. 13, 2018.

They further sealed the deal with more lavish nuptials in South Carolina on Sept. 30, 2019, allowing dad Stephen to walk the bride down the aisle and sister Alaia and cousin Ireland to serve as a bridesmaids.

While she swapped her maiden name for her similarly famous married name soon after she and Justin legally wed, it wasn't a decision Hailey took lightly.

"It took some getting used to, for sure," she told Bustle in 2019. "It's definitely strange, it takes adjusting."

Growing up a Baldwin, she added, "I'm very proud of my family name. I come from a great family with a history in this industry."

All has been going along, the pair marking five years of marriage last year. But ahead of Justin's 30th birthday on March 1, Stephen set off alarm bells by reposting a pastor's Instagram Reel plea to have people pray for the couple. It remains unclear if he was just idly sharing or there's something specific that could warrant a call for good vibes.
