Eve Hewson gets her strong work ethic from father Bono

Eve Hewson admits no one has any idea how much graft goes on "behind the scenes" for actors and musicians.

The 33-year-old actress - who is the daughter of U2 frontman Bono, 64, and his activist wife Ali Hewson, 63 - says witnessing her rock star dad work all hours of the day for his "entire life" rubbed off on her.

She told Byrdie: “I grew up seeing my dad work all day.

“Every day, from the moment he woke up at five o’clock in the morning, he would get up, write for two hours, and then read, and then start his phone calls. And he did not stop working until he fell asleep at 10 o’clock at night. I’ve seen him do that for my entire life. Of course, when I was younger, he would come home a lot later because they used to record late into the night.”

The 'Bad Sisters' star - whose younger brother, Elijah Hewson, 25, is the frontman of indie band Inhaler - says people only see a small snapshot of what makes celebrities successful and insists it's not all partying and living it up.

She said: “I’ve seen how much work it takes behind the scenes that people don’t understand or recognise. The success people see in magazines or online, or wherever they’re getting their information, is such a small amount of the work actually going on. And that’s been a great training ground for me, to know how much you have to commit yourself to something. And I think a lot of young actors don’t have that knowledge; don’t really understand the amount of work put into the craft. Lady Gaga is not actually out partying all the time. She’s working her a--- off."

Eve continued: “Okay, Charli XCX is maybe out a little bit more than Lady Gaga, but she’s not actually partying all the time. These people work. They’re dedicated to their craft. But you only see a tiny bit of that when they become successful.”

The 'Perfect Couple' star's parents were not best pleased to hear she wanted to become an actor, and Eve admits there is "a lot of bad s---" that goes on in "stark" Hollywood.

She said: “[My parents] were like, ‘Oh my god, this is what she wants to do.’ They just didn’t want me to move to Hollywood. They didn’t want me to get caught up in the movie business.

I mean, look at the music industry, at the movie industry—it is stark. There’s a lot of bad s--- out there. They were concerned for their 15-year-old child that, all of a sudden, came home and was like: 'I want to be an actress'. They were like, ‘Oh god, no. Please be an architect.’”
