Kill ‘em with kindness!

When Jennifer Aniston, 41, met sexy Just Go With It costar Brooklyn Decker, 23, she was all smiles.

“The first time we met, she came up to me and gave me a big hug,” the Sports Illustrated swimsuit model tells Entertainment Tonight. “She’s been like that the whole way. Someone in her position doesn’t have to be that way and she is.”

A set source told Us Weekly that Aniston is “intimidated” by her younger costar. “She’s very conscious of her body…She’s obsessed with staying fit and young.”

Toward that end, the 5-foot-6 actress “rarely misses a workout” no matter where she is, the source says. In between scenes for Just Go With It (in which she flaunts her bod in a hot-pink bikini), the 5-foot-6 single star hit the gym for at least an hour daily, sipped pureed papaya, pineapple and mango and dined on veggies and fish.

Looks like the hard work paid off. “She’s stunning,” Decker gushed. “She’s such a great mix of beautiful and kind.”

Adds Decker: “The most surprising and amazing thing about her is she treats everyone like she’s been best friends with them for years.”

She wore an itsy-bitsy hot-pink bikini…

Last Thursday, Jennifer Aniston shot another scene for Just Go with It on the Hawaiian island of Kauai — wearing close to nothing.

Shooting near a tropical waterfall, the 41-year-old actress wore a barely-there, hot-pink bikini. The tan star’s super-sleek physique is no accident. “She’s obsessed with staying fit and young,” a source says in the latest Us Weekly.

And Aniston has another incentive to look good on the Just Go With It set: 23-year-old costar and Sports Illustrated cover girl Brooklyn Decker. “Jen’s intimidated,” the source says of Decker. “She’s very conscious of her body.”

To keep in fighting form, the 5-foot-6 actress spends at least an hour (sometimes more) daily at the gym at the Four Seasons in Maui — sweating it out on the treadmill and elliptical.

“I saw her on the treadmill, and it was angled all the way up,” one Four Seasons guest recalls. “I couldn’t do that for one minute!”

I’ve added a few high quality photos of Jen in her pink bikini on the set of ‘Just Go With It’ !

I’ve updated the gallery with scans of the June issue of Inland Empire Magazine featuring Jennifer!

Jennifer Aniston shows off her tight tummy in a new ad for Smart Water.

“Working out feels great…afterwards,” the ad’s copy reads. “That’s why I drink Smart. It’s hydration I can feel. (And it’s one part of my routine I never sweat.)”

Jen has denied being put on the baby food diet by Gwyneth’s trainer, Tracy Anderson.

“Sorry, but the last time I had baby food, I believe I was 1,” she told People. “I’ve been on solids for about 40 years now.”

(As if we didn’t know!)

Actress Jennifer Aniston has gone on record to deny rumors that she is eating a diet of baby food.

Aniston is currently hanging out in Hawaii shooting her new movie “Just Go With It,” in which she stars across from funnyman Adam Sandler.

While some baby food maybe tasty, she insists that she is not living off of it: “I’ve been asked lately, ‘Jen, what’s this baby food diet all about?’” she says. “I kept thinking: That’s the strangest question ever.”

The diet in question, involves eating up to 14 servings of baby food during your day, followed by a healthy dinner.

“Sorry, but the last time I had baby food, I believe I was 1,” she added.

On Friday’s episode of The Dr. Oz Show, stars get a chance to ask Dr. Oz a question. Among the celebs: Mary J. Blige, Patti LaBelle, Carrie Ann Inaba, Trudie Styler, Martha Stewart and Jennifer Aniston, as shown in this clip.

Jennifer and Adam continued filming in Maui on May 11th while they hung out on the island between scenes. I’ve updated the gallery with photos.. enjoy!

Busy times for Jennifer Aniston’s agent. This morning, The Hollywood Reporter and Variety announced that the former Friends star is circling two new big-screen projects. One is Horrible Bosses, a workplace murder comedy also likely to star Jason Bateman, Charlie Day (a Mandi Bierly favorite), and Colin Farrell. Aniston would play an aggressive dentist who hits on the hapless Day character. Seth Gordon (Four Christmases) will direct. Sounds promising, right? My fingers are crossed that it’ll be similar in tone to what remains her best movie to date: Office Space.

TPS reports indicate that Project No. 2 has even more potential. Also a comedy, this one’s called WanderLust and it’s got an impressive pedigree: Judd Apatow is producing, David Wain (Role Models) is directing, and Paul Rudd is costarring, co-writing, and producing. Paul Rudd bustin’ out the triple-threat cred! To me, that’s reason enough to root for this movie, which, by the way, tells the story of a couple who moves to a commune after losing all their moolah. But it also has that Apatow guy attached, as well as David Wain, who certainly knows how to bring the funny, especially when Rudd’s around. I give you: Wet Hot American Summer.

Anyway, back to Rudd. Whatever you thought of his and Aniston’s last outing (other than his guest-starring turn on Friends, that is), 1998′s The Object of My Affection, they were cute on screen together. (See inset!) And for the love of Rachel Green, isn’t it time Aniston got paired up again with an actor worthy of her specific brand of comedic talent? (I’m lookin’ at you, Gerard Butler!) Her flustered everygal charm and his adorable goofball wit seem like a solid match to me. And so, I ask you, could WanderLust be the hit that Jennifer Aniston’s been looking for all these years — or at least since The Break-Up? (I liked Marley & Me and it made a ton of money, but she was second fiddle to Owen Wilson and the dog.) My hopes are high. Yours?
