Simpson, 32, is currently in Hawaii with her family, fiancé Eric Johnson and their daughter Maxwell Drew, People reports.

This voluptous photo is just the latest in a string of Twitpics from Simpson. On Dec. 26 she tweeted "Aloha…" with a picture of her and Johnson.

Oh Christmas Day, Simpson also offered a photograph of her daughter lying in the sand in front of message that read "Big Sis," which was meant to signal Simpson's latest pregnancy.

Aside from anxiously awaiting Simpson's next Twitpic, fans can find her on the cover of the January/February 2013 issue of Weight Watchers magazine in which she talks about her diet.

“I’m crazy about smoothies, so I bring fruit chopped up and ready to go," Simpson told the magazine. "That way, I can sip the same smoothie all morning long between takes. If it thins out, I put it back in the blender with crushed ice for a few minutes.”
