Baby #2 is on the way for Jessica Simpson and Eric Johnson! The 32-year-old singer and fashion designer let her 7-month-old daughter Maxwell Drew deliver the good news by posting a photo on Twitter of the infant next to the words "Big Sis" written in the sand. "Merry Christmas from my family to yours!" Simpson wrote. What a way to make a happy holiday that much happier! Congrats to the growing family.

Plus, see more moms with their tots!
