Anna Faris has addressed those Chris Pratt and Jennifer Lawrence cheating rumours.

The 'The House Bunny' star admitted while it wasn't true that her 'Jurrasic World' actor husband had been cheating on his 'Passengers' co-star she said it was ''devastating'' and had a ''blindsiding'' affect on their ''incredible relationship''.

She said: ''It has been a little devastating. For us it was like, 'What the heck.' This has been blindsiding to us. We have an incredible relationship. [But] it has been weirdly stinging.''

The 38-year-old actress was hit ''harder'' by the hearsay because she'd always believed in gossip about celebrities and their affairs.

She told Fox News: ''[That] stung a little bit harder than I 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, the blonde beauty isn't going to let false accusations get her down and she is still very much in love with the father of her two-year-old son, Jack Pratt and is ''very lucky'' to be with someone who takes family seriously.

She added: ''I am very lucky that I am with a man that we both value family.''
