Gwyneth Paltrow is reportedly losing weight at a speed that her boyfriend, American Horror Story producer Brad Falchuk, is not okay with.

According to a new report, the 43-year-old actress and mother of two had dropped a substantial amount of weight due to her crazy eating habits, and her 44-year-old boyfriend is begging her to start eating a healthier diet.

“On Gwyneth, a 5 lbs weight loss really shows, which is why she’s been wearing big sweaters and billowing dresses,” a source told OK! Magazine on Thursday. “Brad doesn’t like it and prefers her to have more meat on her bones.”

The source went on to allege that Paltrow has even gone to strange lengths to hide her weight loss, and often countours “makeup done on her chest to minimize how bony it looks." 

As for what has led to Paltrow's weight loss, the source claimed she's been “skipping the occasional odd meal” due to stress from her ex-husband, Chris Martin.

“Gwyneth’s had a lot on her mind lately, from Chris’s reluctance to introduce his new girlfriend to finding her next big project,” the insider said.

While things between Paltrow and Martin, who consciously uncoupled in March of last year, may be a bit tense, they put their personal issues aside on Thanksgiving, and were seen celebrating together with their two children, Apple, 11, and Moses, 9.
