His mum and dad keep up-to-date with Westwick's American adventures by scouring the internet for stories about their son - and they often quiz him about the gossip.
He tells Britain's Company magazine, "It's very bizarre. There are things written that you wish weren't, things that aren't anyone else's business. At first it was weird, surreal, frustrating, but if people want to print s**t they're going to print s**t.
"My mum and dad scale the internet 24/7 so the stories bother them more. I speak to them three or four times a week but they're always like, 'I saw this picture of you, what's going on?' They're funny."
