Shanna Moakler and Kourtney Kardashian's feud is far from over! Far!! Travis Barker's ex wife has long criticized his current wife's style of parenting and way of life. It's no secret that these two don't get along very well - and now Shanna is adding fuel to the fire! The 50-year-old, of course, shares Landon, 22, and Alabama, 20, with the Blink-182 drummer. This makes Kourt their stepmom, and that's clearly not been something Shanna's been okay with for a period of time.
