Michael has previously dealt with his own struggles with alcohol, but insists he never drank around his four children.
He added to RadarOnline.com: "Not once in my life did I ever drink around my kids."
Michael also claimed that Dina has caused problems in his relationships with Lindsay, 25, and her three siblings, Michael Jr., 23, Ali, 17, and 15-year-old Cody.
He said: "I can't get in touch with any of my kids because when Dina is around no one talks to me.”
