Victoria Justice Pays Tribute to Her Nickelodeon Days with SpongeBob PJs for Her 31st Birthday Bash: 'ThirtyOnesie'

The 'Victorious' alum topped off her comfy, festive look with a sparkly crown

Victoria Justice is adding another candle to her birthday cake — and her Nickelodeon legacy continues to shine brightly.

In celebration of turning 31 on February 19, the Victorious alum paid homage to her past by wearing a SpongeBob-themed onesie paired with a sparkling purple crown. Sharing moments from her birthday bash on Instagram, Justice posted pictures of herself rocking the throwback ensemble.

The first photo in the post pictures her alongside her younger half-sister, Madison Grace Reed, who also sports a onesie while posing with a dog. Another snapshot in the carousel shows Justice kissing a blue version of Michelangelo's famous David statue.

"#ThirtyOnesie 💘🎈," Justice captioned the post, encapsulating the fun and nostalgia of her celebration.

"So nickelodeon of you," one user commented on her post.

Other pictures from her post capture the rest of the actress's friends also decked head-to-toe in pajamas.

"Oh my gosh! You are too adorable 😍 I’m turning 31 as well in March and I kinda wanna steal the onesie idea for my party lol," someone replied to the actress' post.

Earlier in the week, Justice posted another photo on Instagram wearing a red, ruffled dress to kick off her birthday celebrations. In the picture, the actress poses gracefully in front of a white backdrop with one of her arms in the air.

"Happy b day to me ☺️🎈Thank you all for the b day wishes, means more to me than you know!! Sending you all so much ♥️" she captioned the post.

Justice's birthday celebrations this year also follow her decision to get her first-ever tattoo at the CURATEUR Retreat hosted by Rachel Zoe and Chriselle Lim after turning 30 last year.

In a photo taken at Calamigos Guest Ranch and Beach Club in Malibu, Calif., in March 2023, Justice smiled after getting her new ink — a dainty heart on the inside of her arm — done by Ephemeral Tattoo.

A couple of Instagram Stories shared by the tattoo studio show the Victorious alum putting on a brave face while getting tattooed, as well as her flexing her muscles to show off the end result.
