Sharon Stone congratulates son Laird with sweet photo from his first day at University of Utah: 'Big day'

Sharon Stone is one step closer to becoming an empty nester.

The Academy Award nominee, 66, saw off her 19-year-old son Laird Vonne on Thursday with a photo of his first day at University of Utah, where he's studying medicine.

'Big day @la1rds off to university,' Stone captioned the post

Her post comes after the proud mom celebrated Laird's high school graduation in May with a photo the two of them at the ceremony.

Last week, Stone shared a sunset beach snapshot of herself and Laird. 'Last trip before college,' she captioned the photo

Stone is also adoptive mother to Roan Joseph, 24 — whom she shares with ex-husband Phil Bronstein — and 18-year-old Quinn Kelly.

The Casino actress shared a rare photo of all three of her sons locked in a group hug back in June. 'My boyzzz,' wrote Stone in the caption.

Meanwhile, Roan is following in his mother's acting footsteps, recently appearing alongside Sharon and Andy Garcia in the film What About Love.

Sharon posted a behind-the-scenes photo of her oldest son back in May, posing shirtless for a mirror selfie in his wardrobe trailer.

'ROAN JOSEPH STONE / DAY 1 on set. Welcome to the family biz kid, have fun,' she captioned the post.

She previously opened up about losing custody of Roan as a kid because of her risque role in 1992's Basic Instinct. 

'Because you saw this quarter of a frame up my skirt, they wanted to diminish me as a human being, me personally, the woman who played the part,' she explained on The Louis Theroux Podcast in March. 

'And I mean, I lost custody of my child over that,' added Stone. 'The judge said that I made sex films. The judge asked my tiny child if he knew that his mother made sex films. I was in shock.

'I ended up in the Mayo Clinic with an extra heartbeat in the upper and lower chambers of my heart, 'cause I just stopped eating.'

Stone said, 'I didn't even know what was happening to me. I was just so confused that I could play a part for three months and lose my child. 

'I could be so good at playing a part in a movie that I could lose custody of my child.'
