Eva Longoria is "desperately trying to get pregnant", says 'Desperate Housewives' creator Marc Cherry. The actress - who plays Gabrielle Solis in the hit US TV show - is said to be determined to start a family with her basketball player husband Tony Parker.

Marc told Us Weekly magazine: "Eva is desperately trying to get pregnant with Tony. After they phone their doctor, she promised me I will be the next call!" The new 'Desperate Housewives' series is giving Eva the opportunity to practice her mothering skills. Set five years in the future, Eva's character is now a mother of two.

Marc added: "Gaby is having a very tough time being the mother of two overweight, hyperactive children. But Eva is having a marvellous time playing her!" Eva previously revealed Marc had banned all pregnancies on the set after her co-star Marcia Cross conceived twins and the pregnancy had to be written in the script.

She said: "You know when Marcia Cross was pregnant? Marc Cherry came on the set and he was like, 'No more pregnancies this year! They're really hard to write in!' "
