Rumer Willis just paid tribute to her baby girl permanently.

Bruce Willis and Demi Moore’s eldest daughter honored the birth of her daughter, Louetta, with a new tattoo.

The proud new mother, 36, opted to commemorate her daughter’s birth date by having the day “4-18” tattooed on the side of her wrist, showing off the design on Instagram on Monday.

Rumer welcomed baby Lou in April 2023 with her then-boyfriend, Derek Richard Thomas, though the actress revealed that the pair split last month.

The “Die Hard” actor’s daughter visited Uplift Tattoo in New York City on Sept. 9 for the new ink by Jacquelyn Maroney, who has previously inked celebs like T.J. Holmes.

Rumer didn’t stop at the simple birth date design, she also added another piece of body art to her collection on the same day.

Rumer added a miniature seashell design, which she matched with her friend, jewelry designer Mia Moross.

The 36-year-old had the seashell inked near the date of her daughter’s birth alongside her wrist, while Moross opted for her inner bicep.

“All my mermaid dreams came true thanks to @jakkichantattoos,” Moross captioned the post revealing her inner arm tattoo.

While at the tattoo parlor, Rumer rocked a blue tank top complete with a blue-and-white striped maxi skirt.

She tied her ensemble together with New Balance sneakers and opted for minimal makeup.

This is hardly Rumer’s first tattoo; She has more than 20 designs, including multiple colorful stars and symbols on her wrist.

While the “Masked Singer” star has plenty of ink on her arms, back and various designs around her body, there are a few designs she’s had removed over the years.

A large lion’s head is now missing from her upper arm and the sweet “Dancing With the Stars” tribute she had added after winning the competition show in 2015 was removed three years later after a breakup with her pro partner Val Chmerkovskiy.

We know there’s no way Willis will part with this new ink.
