BEVERLY HILLS, Calif. – Anna Faris is finally speaking out about tabloid reports that her marriage to movie mega-star Chris Pratt is on the rocks.

“It has been a little devastating,” the “Mom” star told FOX411. “For us it was like, ‘What the heck.’ This has been blindsiding to us. We have an incredible relationship. It has been weirdly stinging.”

In July, Star magazine reported that Faris, 38, was concerned her husband of six years would cheat with his sexy new co-star, Jennifer Lawrence.

“[That] stung a little bit harder than I thought it would,” she admitted. “I have always kind of believed that part of the rumors of celebrity couples were sort of true — because they had never been a part of my life. I thought ‘Maybe there is a kernel of truth to that.’”

Farris and Pratt first met in 2007 when they starred together in the big screen comedy “Take Me Home Tonight.” They married in 2009 and have a 3-year-old son, Jack.

“I am very lucky that I am with a man that we both value family,” she said.

While Pratt is currently filming the sci-fi movie “Passengers” (with Lawrence), Faris is back at work on Chuck Lorre’s multi-generational sitcom.

Season three will include a guest appearance by Oscar-winner Ellen Burstyn.

“She is playing my grandmother — Allison Janney’s mother, who gave her up for adoption,” Faris said.

Faris, who rose to fame in the “Scary Movie” franchise, admits she would like to do more film work, “but I don’t know if they are having me, to be honest.”

“I want to do all kinds of things and my husband and I are working toward that goal,” she said. “We are really hoping to act together in the right project. We are still trying to figure out what that is. But from the day we met, we have been fantasizing about it.”

“Mom” returns Thursday, November 5 on CBS.
