Brad Pitt is reportedly getting worried sick about Angelina Jolie's diet as she continues to lose weight to dangerous levels.

According to the source who dished to OK! magazine, "She's really unhealthy right now, but this is nothing new - he builds her up and the moment she's not under his watch, she stops eating again."

And Brad Pitt reportedly solicited the help of their six children in what is known as a "save mom retreat" where they go off to an undisclosed location and force Angelina Jolie to take on a high-calorie and high-protein diet.

Various reports claimed that Angelina Jolie's weight has dropped down to dangerous 90 pounds.

"But it's not your ordinary binge-eating bonanza as Pitt has sought out a professional to help out Angie along the way. According to our insider, Pitt has enlisted the help of Gertrud Keazor, a retired French fencer who now runs retreats, to 'try and get through to her,'" it said.

Gertrud Keazor is the owner of Yobaba Lounge retreats.

According to its website the retreat house "is a Village Chateau known for its unique style and gorgeous accommodation. Delicious gourmet food, locally sourced, is served. The mostly raw, no grain, no dairy and sugar free creations please the eye and quickly rebalance the body."

It added, "Yoga and meditation support the wellness program. They are taught in our beautiful Yoga studio. Located on the top floor, overlooking the medieval roof tops, and greeting the morning sun, it is a sanctuary of earthy calm."

According to OK! Angelina Jolie will be placed on a special diet designed for weight gain "along with private 1-on-1 sessions with Keazor."

"The goal is to build her up and teach her new eating habits," the source claimed. Apparently, Brad Pitt wants Angelina Jolie "to totally pig out, like he wishes he could."
