The singer, who has been vacationing in Hawaii with hubby-to-be Eric Johnson and baby girl Maxwell, continues to show fans how awesome her tropical getaway is through various twitpics.
And the latest one also added some major cleavage.
"Fun in the sun...," a fresh-faced Jess tweeted, while wearing her cowboy hat, a bright red tunic dress and, clearly, a pair of very heavy sunglasses.
Just yesterday, Simpson was spotted taking a stroll along the beach with Johnson, wearing what seems to be the theme of this trip—her cowboy hat and another colorful tunic (she's definitely keeping that bump underwraps).
But that time, her naughty pillows were fully covered.
