David Cassidy's nephew, Jack Cassidy, stuns Adam Levine, Alicia Keys on 'The Voice'

Where one journey ends, another begins!

Just a few days after his uncle, David Cassidy, performed his last-ever concert, 18-year-old Jack Cassidy made his official debut. The teenager stunned on Monday's episode of "The Voice" with a rendition of Joan Osborne's "One Of Us" -- and he didn't need the family name to do it!

The beautiful performance is a much-needed positive update for the Cassidy clan. David, who's made headlines over the years for substance abuse, legal problems and a tumultuous relationship with his family, revealed in February that he's battling dementia.

Thankfully, the ongoing family drama had no impact on the younger Cassidy's stellar audition! Alicia Keys and Adam Levine both swiveled their chairs and began competing for his loyalty without having any clue that he's a "Partridge Family" descendant. It wasn't until Keys specifically asked him about his background that he disclosed the info.

Before his audition began, Cassidy explained why he was resistant to reveal his last name. "I love that the coaches don't my name; they don't know anything about me," he said. "They're just judging me purely on the merit of my voice."

His grandmother, Partridge matriarch Shirley Jones, shared her own hesitations about Cassidy's entrance into the music world.

"In the beginning, I was not very happy with him going into show business," Jones said. "But, when I saw him sit down at a piano, I didn't even know he could play the piano. Then he started to sing, and I thought, 'You know what? This is a voice that's really remarkable.'"

Cassidy ultimately opted for Team Alicia, a move encouraged by fellow judge Blake Shelton. Shelton pointed out that by teaming up with Keys, the two could put together an incredible piano duet. We can't wait to hear it!
