Chrissy Teigen and John Legend aren't going the way of Brad Pitt and Angelina Jolie, Ben Affleck and Jen Garner, Fergie and Josh Duhamel ... they're in it for the long haul, according to Chrissy.

We got Chrissy coming out of LAX Friday with baby Luna in hand. She blasted InTouch for running a cover story that the two were breaking up.

The couple just celebrated their 4-year wedding anniversary ... and Chrissy knows why it's gonna last.

Oh in touch go fuck yourselves, you exclusively dumb pieces of trash
