Oh Baby!

It's offspring time for actors Matthew Broderick and Sarah Jessica Parker: They're expecting their first child.

Syndicated columnist Liz Smith reported Friday that Parker, 37, is pregnant, and is due to give birth in the fall. Parker's publicist wasn't immediately available for comment.

The 40-year-old Broderick, who recently co-starred on Broadway in "The Producers," and Parker, co-star of HBO's "Sex and the City," have been married since May 1997.

As a result of the pregnancy HBO is temporarily shutting down production on the award-winning program for a little while as it figures out how to work around Parker's pregnancy.

The new season for her show was scheduled to start in June. That's been pushed back to July.
