Desperate Housewives star Eva Longoria Parker has once again been forced to deny she is pregnant - as rumours over her supposed baby bump refuse to go away.

The actress has been dogged by speculation she is expecting her first child ever since she married basketball player Tony Parker last year (07).

And the rumours have escalated in recent months after the star was seen sporting a newly expanded figure.

But Longoria Parker puts the change in her appearance down to simple weight gain, which she was required to achieve for her character in the hit U.S. show.

She says, "I'm not pregnant. I'm just fat. I gained 5lb over the summer so instead of a size zero, I'm a size one." (c) WENN
