Jessica Simpson's publicist denies that she is expecting, but gossips point to the physical changes in the stars body.

Jessica’s breasts, for example, seem to be expanding, says another source.

“Her breasts are positively huge, and she really seems to be taking care of herself.

“She’s not saying anything one way or the other when the subject comes up, but women who put on weight don’t smile when someone suggests they might be pregnant,� added the source.

Jessica Simpson is dating singer John Mayer . The relationship between the pair has been tumultuous reports US Magazine. “They’ve broken up and gotten back together about 15 to 20 times,� a Simpson insider tells Us.

On May 18 the couple officially called it quits, but were together at her NYC hotel just two nights later. Sources confirm to Us that the split is more of a question mark than an exclamation point. And experts say their sporadic status suggests that the rocker is toying with his love.

“It may be a reflection of his own ambivalence about being in a relationship,� L.A. psychologist Yvonne Thomas tells Us. It’s a painful situation for the sexy divorcee, but Jessica is far from the only woman out there who has to deal with relationship mind games. “Women who are not very secure or are still finding their identity� are more likely to try to please their significant others, Thomas adds."
