Kelly Preston and John Travolta are co-producing a new project: Baby No. 2. “I’m pregnant!” Preston told host Jay Leno on Wednesday’s “Tonight” show. “I’m almost three months. I’ve got a very ‘hiding’ type of shirt on,” said Preston, 36, who is Kevin Costner’s co-star in the new film “For Love of the Game.” She and Travolta, 45, married in Paris in 1991. They have a 7-year-old son, Jett Travolta.
