Hayden Panettiere's brother Jansen has died at the age of 28, according to news outlets in America.
The young brother of the actress - who also starred in multiple Hollywood movies and hit TV shows - is believed to have passed away over the weekend in New York.
It's reported The Walking Dead actor died in New York, according to a family source.
Jansen, 5 years Hayden's younger, appeared in multiple features throughout the early 00s, like Shia LaBeouf's TV show Even Stevens, Ice Age: The Meltdown and a recurring role in Nickelodeon's The X's.
TMZ reported the actor's death this evening - adding how Jensen's cause of death is not yet known.
Jansen's family are yet to confirm the news publicly.
Over the weekend, prior to his reported death, Jansen shared a new snap of his latest artwork - a post fans have now used to pay tribute to the late star in the comment section.
The late star often promoted his graffiti inspired artwork on social media and had a dedicated site for his creative endeavor - with some proceeds from his art sales going to help those in Ukraine.
"I started painting my problems which became my solution. 3% of all purchases goes to #@weareallukrainians2022," the Instagram bio for Jensen's art page reads.
The Instagram profile includes snaps of graffiti-embellished trainers, backpacks and Jensen proudly posing by some of his artwork.
The website for the r.a.n.e brand explains: "I AM a good person. I don’t do anything illegal illegal or at least I don’t do illegal things that hurt people in front of me, if that makes sense.
"I’ve done drugs but I don’t steal. Not to say that anyone that’s ever stolen something is a bad person and far from it. Meaning I have my moments like everyone else.
"I was frustrated with the whole acting thing so I would take it out on weird things things like clothes, like ugggggggg sneezing into a white shirt 'try to get that stain out!' Drop shirt."
Hayden and Jensen once worked together back in the early 00s, with the siblings both appearing in in 2004's Tiger Cruise and 2005's Racing Stripes.
Jensen continued his acting career throughout the 2010s and enjoyed cameos on shows like The Walking Dead and Major Crimes.
The late star was linked to four projects at the time of his reported death over the weekend.
Hayden would often share snaps of her younger brother on social media over the years - including a sweet snap of Jensen in 2021 as she shared a tribute to her young daughter.
The actress took to Instagram with a selfie of her and Jansen in Tahiti. "Sibling time at the amaaaaazing market in #Tahiti," she captioned the sweet sibling shot. "#OceanDiaries @jrpanettiere."
While their faces were mostly hidden behind masks amid the coronavirus pandemic, fans spotted Hayden's accessory: a gold necklace that spelled out Kaya, the name of her seven-year-old daughter with ex Wladimir Klitschko.
