Cameron is dating Jen's ex Paul Sculfor, and Jen is famously dating Cameron's ex John Mayer.
"Jen thinks it's funny she and Cam have swapped boyfriends," a source told Grazia magazine.
"But she is convinced that they have both wound up with the right guy. Jen had a lot of fun with Paul, but knew he was never going to be the right man for her.
"She's been thinking about settling down again and didn't get the same vibe from him."
How does Cameron feel about the switcheroo? She thinks it's "hilarious" - and has no regrets as apparently she's found a winner with the hunky Paul.
"Cameron isn't usually one for public displays of affection so everyone reckons she is falling hard for Paul," said an 'insider'.
"It's early days, so there's no telling where it will go, but they obviously feel very comfortable with each other."
What is it about these 'insider' quotes that sound totally dumb? They may as well have printed 'An insider said Cameron is a lady with blonde hair' for all the information they seem to impart.
