Former NFL quarterback Tom Brady revealed Tuesday that his dog Junie is a clone of his late pet Lua, who died in December 2023.

Brady had blood collected from the aging pit bull mix before her death and used it to create an identical copy through Colossal Biosciences, a Dallas-based biotech company where he serves as an investor, People reported.

“A few years ago, I worked with Colossal and leveraged their non-invasive cloning technology through a simple blood draw of our family’s elderly dog before she passed,” Brady said in a statement, according to the outlet.

The announcement came as Colossal acquired Viagen Pets and Equine, another biotech firm that previously cloned dogs for celebrities including Barbra Streisand and Paris Hilton. Viagen holds exclusive licensing to technology developed by Scotland’s Roslin Institute, the lab that cloned Dolly the Sheep in the 1990s.

Brady shared Lua with his ex-wife Gisele Bündchen and their children Benjamin Rein, 15, and Vivian Lake, 12. The dog appeared in Brady’s 2014 Ugg Australia commercial and was a regular fixture on his social media.

Bündchen announced Lua’s death on Instagram on Dec. 23, 2023, writing, “Our little Lulu, our guardian angel is gone to heaven.”

Brady said Colossal “gave my family a second chance with a clone of our beloved dog.” He added that he is “excited how Colossal and Viagen’s tech together can help both families losing their beloved pets while helping to save endangered species.”

Colossal gained attention earlier this year for claiming it produced three genetically-edited dire wolf pups and announced progress in September on bringing back the extinct dodo bird.
