Jessica Simpson's daughter has the news all spelled out: "Big Sis".
Simpson tweeted a photo of her baby daughter Maxwell playing in the sand, along with the words "Big Sis".
The 32-year-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.
