London, Feb 08 (ANI): Rumours are abuzz that the reason behind Jessica Simpson's sudden 'weight gain' is pregnancy.
According to pals, the sexy actress and singer might be expecting a child with her boyfriend, Dallas Cowboys hunk Tony Romo, 28.
"She hasn't been packing on the pounds because she's over-eating," the Daily Star quoted a friend, as saying.
"The big rumour from her inner circle is that a baby could be the reason she's carrying some added weight," the friend added.
Jessica, 28, has admitted she's 25lbs heavier than she was six months ago but she has refused to respond to hints on late-night TV chat shows about her new belly bulge.
"The reason for that is simple," her pal said.
"I'm sure she and Tony aren't ready to say she's pregnant yet because they don't want to announce it till later in the pregnancy for fear they'll jinx the birth.
"Those closest to them almost certainly know the truth but they will have been sworn to secrecy.
"Just like her, they're having to bite their bottom lips and keep mum," the pal added. (ANI)
