Hollywood couple John Travolta and Kelly Preston have raced to fellow Scientologist Tom Cruise's support as he and fiancee Katie Holmes plan a controversial silent birth in the coming days. The heavily pregnant actress plans to adhere to strict Scientology rules and give birth without screaming obscenities or making loud noises. But the Travoltas insist the birthing procedure, which has been mocked in the press over the past few months, isn't like people think. The PULP FICTION star says, "There are unwanted emotions and pain that goes along with any birth." Preston insists the Scientology-friendly labour doesn't forbid the mum-to-be from yelling out in pain: "Screaming is fine... It's the words. If you can avoid saying certain phrases and words... Just try to keep it as quiet as possible. "Of course you're going to groan and yell. It hurts. Just keep it to a minimum."
