Anna Faris worried Chris Pratt will cheat on actress with Jennifer Lawrence?

A celebrity gossip website has come up with claims that American actress/producer Anna Faris is concerned about actor husband Chris Pratt and Academy Award-winning actress Jennifer Lawrence working together in a movie.

According to Star magazine, the 38-year-old actress is worried that the Jurassic World star might cheat on her with the 24-year-old Hunger Games star, who is his co-star in the upcoming sci-fi movie Passengers.

"Chris and Jen recently had dinner to talk about the movie, and ever since, he hasn't been able to stop raving about how cool Jen is. They share the same goofy sense of humor and make each other laugh," an alleged source said.

"Anna's a very sweet girl, so rather than lash out in jealousy, she's going to play this very carefully. She plans on becoming fast friends with Jen before her filming begins, in hopes that she'll think twice before messing with this married man!" the insider added.

Pratt and Faris met while working on the 2007 film, Take Me Home Tonight. The pair tied the knot in 2009.

The couple celebrated their sixth wedding anniversary on 10 July, and exchanged sweet tweets to each other on the microblogging website.

During an interview on social news site Reddit, Pratt gushed about Faris.

"Anna and I are meant to be together. Our relationship has made me believe in divine intervention and destiny, just as much as my crazy career and the way I fell into this life. She and I grew up 20 minutes away from each other but never met until we met in LA," he said during the Ask Me Anything' (AMA) session.

"We both got our start in horror spoofs. We both did an animated movie for Phil Lord and Chris Miller. We both made our careers playing guileless nitwits for laughs. We both have parents that have suffered with MS. The similarities go on and on. Anna is a great wife. Very patient and understanding. Very supportive. So kind and genuine always. And she gave me a wonderful son and family of in laws that I truly love," Pratt added.
