Prior to Season 15, Bello and Annaliese both auditioned for America's Got Talent individually. Bello auditioned in Season 12, where he was eliminated in the Judge Cuts, but was brought back to the Quarterfinals as a Wild Card, where he got eliminated again. In his audition, he did tricks on a tall swaying pole, in the Judge Cuts, he shot himself out of a cannon over a helicopter, and in the quarterfinals, he performed on a Wheel of Death.
A year later in Season 13, Bello's daughter Anneliese auditioned, where she placed herself in a box what was going to explode, and she had to exhale at the right time to prevent her lungs from imploding. She succeeded and made it past the audition round, but had to drop out prior to the Judge Cuts.
The two joined forces and participated in the first series of Britain's Got Talent: The Champions where they won the Superfan vote in their episode and finished in the top 10 of the final.
Due to the COVID-19 Pandemic, Bello & Annaliese Nock's audition in Episode 1507 was virtual. It consisted of Bello driving a motorcycle on a high wire, while Annaliese did tricks on a trapeze that was hanging below the motorcycle. Simon Cowell, Sofia Vergara, Heidi Klum, and Howie Mandel all voted "yes", sending Bello & Annaliese to the Judge Cuts.
Bello & Annaliese Nock's performance in Episode 1509 was pre-recorded due to how dangerous it was. Unfortunately, the day before they were supposed to perform, Bello suffered a back-related injury, forcing Annaliese to come up with a solo routine. Annaliese performed their planned Wheel of Death act solo including tricks blindfolded, a jump rope, and with the wheel set on fire, all set to "Go Big or Go Home" by Chuxx Morris. Howie Mandel, Heidi Klum and Sofia Vergara gave them standing ovations. They did not receive enough votes to advance to the Semifinals in Episode 1510, eliminating them from the competition along with Michael Yo instead of Archie Williams.
After The Show
Bello & Annaliese performed together in the semi-final round of the second season of the TBS competition series Go Big Show but did not receive enough points to advance to the finale, losing to bull leaper Manu Lataste.
