Qantas Airlines pilot and Grease star John Travolta is jetting home to the States after prematurely ending his participation in the airline's 90^th anniversary celebration. Aussie paper The Herald-Sun reported Sunday that the time has come for his wife, Kelly Preston, to give birth to the couple's second son, who they plan to call Benjamin. Preston, 47, announced the pregnancy in May and was due to give birth on Nov.26, according to her husband, who was greeted in Australia with baby gifts of stuffed koalas and kangaroos. Travolta serves as a goodwill ambassador for the airline and previously said if Preston went into labor during his visit, then he would make the 22-hour trip home, which it looks like he did Sunday. However, reps for the couple debunked the rumors, telling People magazine, "This story is 100 percent false. She's not in labor. John is in route back to the U.S. as was always the plan for him to return this weekend."The couple lost their first son, Jett, when he died in the Bahamas after a seizure in January 2009. After a lengthy hearing that involved Bahamian officials charged with extorting the couple, they dropped the charges in September, citing stress on the family and pregnancy. Benjamin will join big sister, Ella Bleu, 10.
