Actresses Halle Berry and Angelina Jolie are joining forces for their spy thriller, Maude vs. Maude, but according to sources, “bony” Angelina is far from ready.

According to Radar Online, the film’s producers want 

the 47-year-old Maleficent actress to beef up her frail figure for her role. 

Luckily, her 56-year-old muscular co-star is willing to whip the mother of six into buff shape.

“She’s skin and bones!” one source exclaimed. “She knows she needs to put on muscle, and this is the motivator to finally do it. With everything else going on in her life, she hasn’t been able to make her health a priority — but now that her work requires it, she’s out of excuses.”

The source said Angelina admires Halle’s muscular figure. The only way to get the Catwoman actress’ shape is to take pointers from the source.

“Angelina can’t stop talking about Halle’s muscles,” the source added. “She wants some of what Halle’s got, and Halle has agreed to help make it happen.”

Besides her acting talents, Halle is known to be a health and fitness guru who adheres to a strict ketogenic diet.

While it won’t be a sweat for the Kidnap star, it won’t be easy for Angelina, who needs to gain 15 pounds.

“She knows it’s not going to be easy after more than 20 years,” the source explained. “She’s not in her 20s anymore, but she’s willing to do whatever it takes.”

Halle has already taken steps to get her friend in shape to kick ass in the upcoming film.

“Halle’s a fanatic when it comes to food,” the insider shared. “She’s paleo and always trying to convert people, so she was thrilled when Angelina asked for her guidance. She’s got Angie drinking bone broth, loading up on healthy fats and lifting weights. Angie is weak and totally out of shape, but she’s determined to kick butt with Halle’s help.”

It’s good producers didn’t re-cast Angelina because of her figure. She ate and left no crumbs in Mr. & Mrs. Smith and Salt. This duo will surely slay in Maude vs. Maude.
