Gwen said: "Kingston is in that terrible twos. Gavin calsshim Sid Vicious. He's like, 'You gave birth to Sid Vicious.'
"He's definitely got an attitude and Zuma is the opposite. He's like this cool, laidback, easy-going guy."
Kingston has inherited both his parents' love of music, and already has a keen sense of the songs he wants to hear.
Gwen explained: "He likes Top 40 hits like his mum. Any song that comes on, he'll get p***ed if you turn the station. He'll be like, 'That's my song! That's my song!' "
Kingston is so destined to be a rock star just like his parents and I love that he already has the 'tude!!! 2 cute!!!
