JOHN'S FEARS FOR ELLA 'I HAVE TO PROTECT HER!

The veteran actor can't help but worry as his daughter starts her big music career

- 

As one of his daughter Ella Bleu's biggest cheerleaders, John Travolta couldn't be prouder to watch her embark on her music career and release her first EP into the world.

But having spent five decades as an actor and singer in the cut-throat world of Hollywood, John, 71, can't help but worry how his daughter will fare in an industry that tends to chew talent up and spit them out.

“John’s doing his best to be supportive, but he does have sleepless nights over Ella’s big steps into the spotlight,” an insider tells Woman's Day.

“He also knows what it’s like to make mistakes in the public eye, and to go through scandals and heartbreaks with all the world’s worst trolls on attack.

“Even though Ella has the advantage of growing up with both her folks in show business, John knows that nothing can prepare you for real fame - and that there's no going back once you achieve that.”
