Birthday cutie! Julia Louis-Dreyfus looked more adorable than ever in a throwback photo she shared to Instagram on her 59th birthday. The beloved Seinfeld star proved she’s ageless as she uploaded the heartwarming snapshot in honor of her special celebration.

“Enjoying my birthday and opening birthday presents back in 1965,” Julia, who would have been 4 in the snap, wrote alongside her post on Monday, January 13. “Not much as changed since then. Thanks for all the happy birthday wishes!” she continued, adding the hashtag “happy birthday to me” at the end of her caption.

In the throwback pic she shared, the Veep actress can be seen donning a sailor’s ensemble featuring a red top and pleated blue skirt. Julia couldn’t help but flash her beaming smile at the camera while opening presents as just a tot.

Fans of the Saturday Night Live star — who is the proud mom of sons Henry Hall, 27, and Charlie Hall, 22, with longtime husband Brad Hall — joined in on the birthday celebrations as they flooded her comments section with sweet messages. “Hope your day was a blast! Happy Birthday, pretty lady!” one fan wrote, while another echoed, “Happy Birthday my queen.” A third fan chimed in, gushing, “Thank you for all the entertaining years and laughter … you look as cute as ever in this picture.”

We bet Julia is feeling extra grateful this birthday considering she’s been on the road to recovery since revealing her battle with breast cancer in September 2017. Although she is in remission following six rounds of chemotherapy, the Curb Your Enthusiasm actress hasn’t been shy about the trials and tribulations she’s faced since being diagnosed.

“I’m still working it out, to be honest with you,” Julia told Vanity Fair about learning to cope with her heartbreaking cancer battle in an August 2019 interview. “I’m glad I got through it, but there’s a part of me that’s still a little frightened, you know?”

Luckily, Julia is back to work and feeling better than ever. In late 2018, a source close to the New Adventures of Old Christine actress revealed how much of a toll her cancer battle truly had on her.

“She won’t tell you this because she tries to be strong, but she was very scared,” the insider exclusively told Closer Weekly. “She’s feeling good! She has more energy and, as she says, ‘verve,’ than she’s had in a long time. She’s thrilled — and very grateful.”

We hope Julia had the best birthday!
