Jessica Simpson is expecting another baby with her fiance of two years, Eric Johnson. The singer confirmed the news today, tweeting a sweet holiday picture of her baby daughter Maxwell dressed in a red and white onesie on the beach, with the words "BIG SIS" scrawled in the sand.

"Merry Christmas from my family to yours!" tweeted Simpson.

Simpson gave birth to Maxwell in May. Speculation that the singer was pregnant again has been growing in recent weeks, after Us Weekly announced the unconfirmed news first in late November.

Celeb-watchers immediately began pondering what a pregnancy would mean for her multi-million Weight Watchers deal. Simpson released a new commercial for Weight Watchers just five days ago, sharing that through their program she'd lost 50 pounds.

But with a baby announcement this adorable, it doesn't look like Simpson is too worried about any of that right now.
