Grant Imahara, best known as the co-host of "MythBusters" and "White Rabbit Project," has died at age 49, multiple news outlets are reporting.
According to the The Hollywood Reporter, the electrical engineer died of a brain aneurysm.
Discovery, the network that aired "MythBusters," released a statement Monday confirming Imahara's death.
"We are heartbroken to hear this sad news about Grant," the network said, according to Variety. "He was an important part of our Discovery family and a really wonderful man. Our thoughts and prayers go out to his family."
Imahara, who also was a roboticist, appeared on the science show "MythBusters" from 2005 to 2014 and Netflix's "White Rabbit Project" in 2016, the news outlets reported.
Imahara's former colleagues, including Kari Byron and Adam Savage, took to social media to pay tribute to him.
"Sometimes I wish I had a time machine," Byron, who also co-hosted "MythBusters" and "White Rabbit Project," captioned a photo of the pair with fellow host Tory Belleci.
“I’m at a loss. No words,” tweeted Savage. “I’ve been part of two big families with Grant Imahara over the last 22 years. Grant was a truly brilliant engineer, artist and performer, but also just such a generous, easygoing and gentle PERSON. Working with Grant was so much fun. I’ll miss my friend.”
