Britney Spears` sons preparing for showbiz career

Los Angeles: Pop star Britney Spears` sons have been learning how to sing and dance by watching her rehearse for her upcoming Las Vegas residency.

The 32-year-old `Perfume` singer is preparing for the start of her two-year residency in Las Vegas on December 27 and says sons Sean Preston, eight, and Jayden James, seven, have picked up plenty from her rehearsals, reported E! online. "Preston, he`s already dancing up a storm. He shows all my dancers how he can dance. It`s really funny. Jayden is actually the singer. He sings a lot," Spears said. The star has been in intensive training for the shows and subjected to a gruelling rehearsal schedule, but is pleased with how things are looking ahead of the grand unveiling. "I`ve been through the wringer. But it`s coming together and it`s going to be worth it. I really feel that this is my best show I`ve ever done," she said.
