Jessica Simpson’s Star-Studded Baby Shower [PHOTOS]

The pregnant star appeared on 'The Tonight Show.'
She’s full of  estrogen and pop tarts with butter, but Jessica Simpson isn’t ready to deliver for another month.  This leaves enough time for a lavish baby shower, put together by Mindy Weiss, the celebrity planner behind Simpson’s Austin wedding to first husband Nick Lachey.

Guests at yesterday’s Los Angeles bash included Jessica Alba, Ellen Pompeo and Ashlee Simpson, who brought their children, keeping the dude count fairly low (though Peter Wentz and Simpson’s fiance, Eric Johnson were present).

Simpson wore a blue maxi dress and her blond hair down with soft braids intertwined to event, which was not a surprise, according to Us Weekly.  “She seemed completely ecstatic,” a source told the magazine.
