It’s been just over a week since Jessica Simpson announced she was pregnant with baby number two, but she’s already flaunting her bump.

The singer-turned-designer took to Twitter while on vacation in Hawaii to show off her ever-expanding belly.

Wearing a bikini and a fun flowered print cover-up, Jessica posed for a self-portrait in the bathroom of her hotel.

Though she was initially keeping quiet about her second pregnancy, she’s certainly ready to show it off now, letting fans know she’s “bumpin’ and proud.”

Jessica isn’t the only one gearing up for baby in 2013. She joins other celebrity moms-to-be like Kim Kardashian, Shakira and, of course, Kate Middleton.
