Penny Lancaster's rock star son

Penny Lancaster believes her son is going to be a rock star.

Penny - who has a 22-month-old boy, Alastair, with rocker husband Rod Stewart - claims her young son is already showing signs of musical greatness.

The 36-year-old model told Hello magazine: "Alastair likes to play guitar with his sister Ruby, who is 20. Rod gets out his guitar and Ruby does too. Alastair gets hold of the microphone and starts singing.

"He also loves soccer and swimming. He seems to be into everything at the moment!"

Penny also revealed she and Rod have made a pact to never spend more than two weeks apart, and she has started turning down work to spend time with her family.

She said: "My priority is to be with my family. I've started looking around for schools for Alastair - we are looking at schools in America and England, so wherever we are he will have a place of education."
