Jennifer Lawrence is as a social media ''voyeur''.

The 28-year-old star has previously shunned the idea of joining sites like Facebook, Twitter or Instagram and doesn't have a public presence on the platforms, but she has not admitted that while she has signed up for the apps, she doesn't want to get the ''backlash'' that can come with it so doesn't post anything herself.

She told InStyle magazine: ''I'm on it. But I'm a voyeur: I watch, I don't speak. There is always so much backlash. So many people are listening and paying attention, and they have so many opinions about absolutely everything.

''I really don't want to welcome that unless it's absolutely necessary. I don't want to put myself out there for no reason. Unless I'm promoting something or something really burns my onions, you won't hear from me.''

It's quite a turnaround for the 'American Hustle' actress, who previously insisted she would ''never'' get an account on social networking sites.

Speaking back in 2014, she said: ''It's fine, I respect that, but no, I'll never get a Twitter. If you ever see a Facebook, Instagram or Twitter that says it's me, it most certainly is not.''

Jennifer has now suggested that time passing has made her more open to certain things, as she added that life ''gets better'' with age, as it becomes easier to navigate with more understanding.

She said: ''Everything gets better as you get older. It's easier to cut through things, and everything gets simplified.

''Physically, everything gets worse. Like, why does my neck hurt? Why are my knees cracking? But emotionally, it gets better.''
