Something to tell us? Jessica Simpson sparked more pregnancy rumours in a loose-fitting top as she left Cabo San Lucas in Mexico yesterday

She denied rumours she is expecting her first child earlier this year.

But it seems Jessica Simpson may just have been keeping mum on her happy news, judging by photographs of the star on holiday in Mexico yesterday.

The 31-year-old star attempted to disguise what appeared to be a baby bump in a loose-fitting animal-print top as she jetted out of Cabo San Lucas yesterday afternoon.


Burgeoning: Jessica has been seen with what appears to be a baby bump as early as July

Jessica was first spotted with a burgeoning bump back in July, when her spokesperson came forward to insist: 'She is not pregnant.'

However, since then, Jessica has been covering up in flowing clothes which have further sparked reports she and fiancé Eric Johnson could be expecting their first child together.

The singer-turned-actress has made no secret of her desire to have a family with former NFL player Eric.

She said earlier this year: 'I definitely see myself having a family with Eric, so that’s exciting to think about.'

The two posed together as they prepared to fly back to Los Angeles and Jessica posted a photo on Twitter with the caption 'Leaving family vacation...'

Jessica and Eric have been on holiday for the past week with her sister Ashlee and friends including Nicole Richie, DJ Samantha Ronson and actress Juliette Lewis.
