Harry Styles and Olivia Wilde are inseparable.
The couple - who reportedly started dating in November and went public with their romance earlier this year - have flown to London together after they finished filming Olivia's movie 'Don't Worry Darling', which Harry, 27, co-stars in.
A source told The Sun newspaper's Bizarre column: "They clearly don’t want to be apart for long, because Olivia, 36, has decided to come to ¬London and is going to be staying with him.
“Obviously things are still early days — they’ve only been properly dating since last November, but things have been moving fast since they went public together at his manager’s ¬wedding."
And the pair are expected to cross paths with Olivia's former fiance Jason Sudeikis, 45 - the father of her children Otis, six and Daisy, four - as he is currently in London filming his TV show 'Ted Lasso'.
The insider said: "The latest move may also mean they all end up seeing each other, as Jason is in London filming his Apple TV sitcom Ted Lasso and ¬currently has his kids by Olivia staying with him, so no doubt there is going to be some crossover among them.
"It’s certainly going to be interesting given the way things have been so far — but nothing is getting in the way for Olivia and Harry just now."
