Julianne Moore’s son, Caleb Freundlich, engaged to longtime girlfriend Kibriyaá Morgan

Julianne Moore provided a rare update on her personal life — her son is engaged.

The “Still Alice” star proudly announced on Instagram Wednesday that Caleb Moore Freundlich popped the question to his longtime girlfriend, Kibriyaá Morgan, who said yes.

“Congratulations Cal and Ki,” Moore, 63, captioned the post, adding red heart emojis. “We love you.”

The Oscar winner shared two sweet photos of Moore Freundlich posing with his new fiancée, who was dressed in a white satin halter gown and grinned from ear to ear while showing off her diamond engagement ring.

The newly betrothed couple, both 26, also shared the news on their Instagram accounts.

Moore Freundlich simply wrote, “it’s pronounced FIANCÉ,” while Morgan shared, “The big kids are getting married!!!! Ahhhhhh I could not love you more if I tried @cal_freundlich YOU AND ME.”

The pair has been romantically linked since April 2017 when they became Instagram-official at an athletes’s formal at the Quarry at Carrigan Farms, a water park in North Carolina.

They met at and matriculated from the nearby Davidson College.

Moore and her husband, Bart Freundlich, who also share 22-year-old daughter Liv Freundlich, joined Morgan’s family for an engagement dinner Wednesday night.

The “May December” star shared a photo of the eight-person group in a wine-filled private room at a restaurant and wrote, “Celebration!!!”

“Best night ever,” Caleb added as he re-shared the image on his own account.

Many of Moore’s famous friends took to the comments section to congratulate the happy couple.

“Congratulations!! Definitely must celebrate over pasta,” wrote “Grey’s Anatomy” star Ellen Pompeo.

“All grown up, congratulations!” commented Jennifer Garner.

“Congratulations! Gorgeous couple, beautiful love,” added Halle Berry.
