"For us it was like, 'What the heck?' This has been blindsiding to us. It has been weirdly stinging," she told FOX411.
She admits the affair gossip stung a little hard than she thought it would.
"I have always kind of believed that part of the rumours 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'."
However, Faris is confident her man will never stray as she and Pratt are so dedicated to building a strong family with their two-year-old son Jack, but she does hope he falls for one future leading lady, because she is searching for a project they can work on together.
"I want to do all kinds of things and my husband and I are working toward that goal. 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 fantasising about it."
