The new E! show, Stewarts & Hamiltons, will feature Sean and Kimberly Stewart, Rod's two grown-up children with his first wife, and Ruby, the rocker's daughter from his relationship with Kelly Emberg.

The show will also feature guest turns by George Hamilton, Alana's ex-husband, and their son Ashley, among others.

The programme will debut in the U.S. this summer (15), and is not expected the feature Rod, his current wife Penny Lancaster, their kids or his children from his 16-year marriage to former model Rachel Hunter.

Meanwhile, Stewart's youngest sons Aiden, four, and Alastair, nine, hit the spotlight on Wednesday (01Apr15) when they joined dad onstage during a gig at the Qantas Credit Union Arena in Sydney, Australia.

The 70-year-old singer, who is dad to eight kids, even passed the microphone to Aiden during a performance of his hit Baby Jane.
