Both stars received tattoos in honor of Waldo Picasso, their young dog who was killed last week in NYC when the animal reportedly got loose from a dog walker.
Waldo was one of two Alaskan Klee Kais owned by Turner and Jonas, with the other being Porky Basquiat.
"R.I.P. my little angel," Jonas wrote alongside a simple portrait of Waldo's face. The art was done at Bang Bang Tattoo in NYC, and prominently featured Waldo's mismatched eyes, as well as his happy attitude.
Turner also showed off her new ink alongside the caption, "I miss you, Waldo. Rest In Peace my little baby."
The two had been photographed everywhere with their beloved dogs over the past couple of years, and Jonas even commented that the pups were more worldly than most humans.
"They have probably traveled more than most of my friends," he joked.
The stars had Waldo for a little over a year, and he was actually the brother of Porky.
When they debuted him to the public in 2018, Turner wrote, "Welcome to the family."
It's unclear if the couple plans on getting another dog after the immense loss.
