Is there trouble in Chris Pratt and Anna Faris' marriage? That's what everyone seems to be guessing, as there's a new report that says Anna Faris is losing weight fast because of all the added stress in her life. Apparently, Faris is none too happy that her husband is now a Hollywood heartthrob with his box office hits while her own career has been taking a downward slide.

According to Star Magazine on Wednesday, the usually happy couple is on the rocks as Faris' stress has been affecting both her health and her happiness.

A source close to the couple dished, "Anna looks tired and emaciated, and she's lost her spark. She's making excuses for not eating. It's got people worrying."

What's more, the newly thin and fit Pratt has been getting a lot of attention from the opposite sex, with Faris worried that he might stray with someone from his female fan base.

The insider added, "Anna doesn't like the way girls hang on him. She liked him bigger, when women didn't lust after him. Her confidence is crumbling as Chris' skyrockets."

What's more, Faris seems to be obsessing over her weight. She revealed a too-skinny frame while on vacation in Hawaii, and critics said she looked frail while promoting the new season of Mom.

The source explained, "People are begging her to take care of herself, but she just laughs it off."

So far, a rep for the couple has denied reports. Pratt and Faris have been married since 2007 and have one child together, their 3-year-old son, Jack.
