Jessica Simpson is expecting again

Jessica Simpson knows a picture is worth a thousand words.

The singer and fashion designer announced her first pregnancy in October 2011 when she tweeted a photo of herself dressed as a mummy -- get it?!

Now, a mere six months after welcoming her daughter with Eric Johnson, Simpson has posted another telling image.

This time the photo isn't of her belly, but her little bundle of joy, Maxwell Drew. Dressed in a festive red and white striped onesie, Maxwell appears alongside the words "Big sis," which are written in the sand.

Simpson's rep confirmed to CNN that the new mom is, in fact, expecting.
