Jessica Simpson tweets a hint of possible pregnancy

NEW YORK - Jessica Simpson's daughter has the news all spelled out: "Big Sis."

Simpson on Tuesday tweeted a photo of her baby daughter Maxwell playing in the sand, with the words "Big Sis" spelled out.

The 32-year-old old singer has been rumoured to be pregnant again. The tweet appears to confirm the rumours.

"Merry Christmas from my family to yours" is the picture's caption. Simpson used a tweet in 2011 to announce she was pregnant with Maxwell. She is engaged to Eric Johnson.
