Jessica Simpson is celebrating her pregnancy shape.

The star, who is expecting her second child with fiancé Eric Johnson, shared a self-portrait of her baby bump on Twitter Sunday.

Dressed in a bikini and a beach wrap that is hanging open, Simpson, 32, writes “Bumpin’ and Proud!”

Simpson has been posting lots of pictures while vacationing in Hawaii with Johnson, their 7-month-old daughter, sister Ashlee Simpson and other family members.

The first picture the Fashion Star mentor shared with fans over this holiday was on Christmas Day: The image of her daughter wearing holiday pajamas and smiling in the sand atop the words “BIG SIS” confirmed Simpson’s pregnancy.
