Aloha, indeed!

Jennifer Aniston wasn't afraid to let it all hang out while shooting a luau scene for her romantic comedy Just Go With It in Hawaii on Wednesday.

The 41-year-old single star showed considerable major cleavage in a cream-colored cut-out, lace-up crochet dress. Just Go With It also stars Adam Sandler and Nicole Kidman, and features a cameo by Heidi Montag.

When Aniston turned 41 in February, she joked to Access Hollywood that she felt ten years younger.

"Thirty-one, pssh. It's quite lovely I have to say," she said. "Thirty was a hump, but you know, 31 is fabulous. It really does get better, doesn't it?"

What she really wants to do this decade is direct.

"I have a project in development I'm going to direct," she told Women's Wear Daily earlier this week. "After you get enough movies under your belt you sit back and go, 'What's next?'"

"It's getting to a time where creatively I want to turn in a different direction."
