Country music star Faith Hill fears for her marriage to fellow rocker Tim Mcgraw, because of their frequent fierce rows. Hill confesses they both take out their stresses and frustrations on each other - and describes their regular conflicts as "horrible". She says, "Sometimes, Tim and I drown in the day-to-day pressures of our careers. "When we become impatient, we sometimes snap at each other, because usually the people you treat the worst are the closest to you. Its horrible. The couple married in October 1996 and have three children together.
