Laura Dern is showering her daughter with big little love on social media.
The Big Little Lies alum celebrated her youngest child Jaya Harper's— who she shares with ex-husband Ben Harper along with their son Ellery Walker Harper, 21,—18th birthday with a sweet Instagram message, showcasing an array of pics of Jaya throughout the years.
"My girl is 18 today!!!," Laura captioned her Nov. 29 post. "Happiest birthday, Jaya! You teach me every day about what it means to be an honest and profound empath, artist, and activist. I love you with everything."
Earlier this fall, on National Daughters Day in September, the 55-year-old gave a shoutout to her youngest with an adorable throwback of the two from when Jaya was a child. "Happy Daughters Day to my girl. My heart," Laura wrote in the Sept. 25 post. "You are the most inspiring person, and what an honor to be your mom!"
The mother-daughter duo have always had a tight bond as back in 2020, Laura dropped in on her Jaya's—who was then 15—TikTok account while she was doing her school work.
"Let's spend our time making a TikTok. You want to make a TikTok? I've got an idea. Let's transform TikTok since I'm homeschooling you," the Enlightened actress said in the hilarious Sept. 15 video when countless parents had to teach their kids from home amid the coronavirus pandemic. "Let's read our homework on TikTok."
Laura then began to dramatically read a passage from her daughter's book, with Jaya captioning the video which has received over 55,000 views, "The only way Laura will get me to do my homework."
However, this wasn't the first time Laura made a guest appearance on her daughter's TikTok, as she also had a cameo in a Dec. 2019 video to Doja Cat's "Say So," while jokingly nudging her daughter out of frame so she could show off her stellar dance moves.
