Joe Jonas and ex-wife Sophie Turner are fighting for custody of their daughters, but he’s keeping them close to his heart – literally – with fresh tattoos.

Last month, after reaching a temporary custody agreement with Turner, the Jonas Brothers star immortalized his girls by tattooing their birth dates on his chest.

The What a Man Gotta Do singer boldly revealed his new body art at his band’s Canadian gig, wearing a white ribbed tank top and a silver beaded choker that sat atop the emotive artwork.

In social media videos and photos, Jonas’ one-year-old daughter Delphine’s birthdate, “07.05.22,” was written on top, while Willa’s birthdate, “07.22.20,” was written on the bottom, divided by a “X.”

But that wasn’t the only new tattoo honoring his daughters that was noticed on the musician, who was already highly tattooed.

Fans also observed a bicep tattoo of a bird, which was most likely inspired by the Jonas Brothers’ song Little Bird, which is dedicated to the brothers’ collective five daughters.

On his arm was also a stick-figure image, likely created by his elder daughter.

Fans gushed over the new tattoo, taking to the comments to express their delight at the singer’s sweet gesture.

“Joe Jonas dad tattoos era,” one X (formerly Twitter) user wrote.

“The tattoos… Joe Jonas loves his daughters so much now lemme [sic] cry this is so pure,” another fan exclaimed.
