John Travolta insists he isn't worried about his 16-year-old daughter Ella's love life.John Travolta won't ''interfere'' in his daughter's love life. The Saturday Night Fever star insists he is ''saving'' his daughter from possible embarrassment because he doesn't question 16-year-old Ella - who he has with wife Kelly Preston - about the boys she hangs out with. Speaking on The Ellen DeGeneres Show, he said: ''I don't interfere with that. I'm saving her because she has two guys that she hangs out with, [and] I don't ask anything about what they say or do with each other. '' Meanwhile, the 62-year-old actor - who also has five-year-old son Benjamin with Kelly - previously revealed his son is keen to follow in his footsteps and wants to star in a movie with his famous dad. He shared previously: ''I took him to Toys 'R Us recently, and he said to me when we got out of the truck and in the cart, 'Why are all these people wanting my photograph?' Because I didn't know if he knew I was in films or not. He said, 'Well, maybe they saw one of your movies!' And he said, 'I want to work with you!' So we'll see how that evolves. I don't want to force [it].''..
