Marcia Cross says she’s desperate to have children — just not her own.

The 43-year-old Desperate Housewives star, who is engaged to businessman Tom Mahoney, 47, says she fears she may to be too old to give birth safely.

So, while she definitely wants to hear the pitter-patter of little feet around their house, she feels it would be safer to either adopt or have a surrogate bear their child.

Marcia believes the evidence is clear that as a woman gets older, there is an increased risk of birth complications. She feels it’s irresponsible to send out a message that you can have a child late in life without any problems. “I don’t like the average woman being misled into thinking that their fertility is something that goes on forever,” said Marcia, who pursued a master’s degree in psychology before landing the role of the Stepford-like Bree Van De Kamp. “One’s own egg only lasts so long, whether I have my own or not, we’ll see.”

Marcia has told pals that she and Mahoney, pictured above, would like to get hitched in Utah sometime over the Christmas holiday as she’s impatient to move in together.
