SARAH JESSICA PARKER struggles not to giggle when her young son throws a tantrum because he likes to watch himself getting upset in the mirror.

The actress is convinced three-year-old JAMES WILKE is a born performer because he likes to see just how upset he can get.

She says, "I do see that my son really likes his own reflection a lot. I actually noticed, recently, too that when he's crying and upset and throwing a very appropriate three-year-old tantrum, which are very brief... he likes to look in the mirror when he's crying.

"He really likes to experience it."
