Jessica Simpson's daughter has the news all spelled out: "Big Sis."
The singer tweeted a photo on Christmas morning of her seven-month-old, Maxwell, playing outside, with the words written in the sand.
Rumours have been circulating for a while that 32-year-old Jessica is pregnant again. The sweet snap appears to confirm the rumours.
"Merry Christmas from my family to yours," is the picture's caption.
Jessica confirmed she was expecting her first baby with fiancé Eric Johnson during a similarly playful post - she wrapped herself in bandages to bress up as a mummy for Halloween in October 2011 and wrote: "It's true, I'm going to be a mummy!"
