Jessica Simpson: "Bumpin' and Proud"

Posted Tuesday January 1, 2013 10:55 PM GMT

Continuing her Hawaiian holiday, Jessica Simpson tweeted a picture of her growing baby bump on Sunday (December 30).

The second time mom-to-be took the photo of herself dressed in a patterned bikini and a floral print coverup with the caption “Bumpin’ and Proud!”

Though rumors about the “Dukes of Hazzard” star's pregnancy began last month, she and her fiancé Eric Johnson did not confirm they were expecting until Christmas Day.

The couple tweeted a picture of their daughter Maxwell in front of the words “Big Sis” spelled out in the sand.
