Married Tinseltown titans Catherine Zeta-Jones and Michael Douglas are expecting their second child this spring, their rep said yesterday.

The raven-haired beauty, 33, and her 58-year-old hubby already have a 2-year-old son, Dylan Michael. 

The pair's announcement comes amid a busy work season for the acclaimed Traffic co-stars, with Douglas set to appear with famed elderly dad Kirk in A Few Good Years, and Zeta-Jones lined up to star in the movie version of Chicago

Douglas and Zeta-Jones married in November 2000, three months after she gave birth to Dylan. 

The stunning little boy, named after poet Dylan Thomas, is the latest in the Douglas acting dynasty to inherit granddad Kirk's classic dimpled chin. 

But his proudly Welsh mom also wants him to retain something from her side of the family, mainly his Welsh roots. So she's bought a million-dollar home in the countryside of Wales, which the family will visit regularly.
