According to Star Magazine on Wednesday, Pratt and Lawrence have been getting along so well lately that the big-screen star just can't stop raving about the actress, who has been famously dubbed as "America's Sweetheart." Unfortunately for Faris though, she's apparently had enough of it.

A source told the site, "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."

To make matters worse, Faris is apparently very jealous of her husband's on-screen chemistry with Lawrence, but she's doing her best to hide it.

The insider added, "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!"

So far, Pratt's team has not responded to the rumors. Keep up with Enstars for all the latest news on Chris Pratt, Anna Faris and all of your favorite celebrities.
