The crooner, 27, who got to know Wilde, 37, while filming their new movie Don’t Worry Darling last year, “started out playing this romance fairly cool, but things have completely changed,” dishes the source.
“It’s gotten to the point where he follows Olivia everywhere he can and barely has any interest in seeing anyone else.”
That has friends worried that the “Watermelon Sugar” singer, who was photographed on a luxury yacht packing on the PDA with the Booksmart director during a recent Italian getaway, could be headed for a rude awakening.
“Harry assumed he’d be calling the shots, especially since it was Olivia who was doing the chasing at first. But he’s turned into her little puppy dog,” explains the source, adding that it might only be a matter of time before Wilde — who walked out on her eight-year romance with ex-fiancé Jason Sudeikis, 45, with whom she shares kids Otis, 7, and Daisy, 4 — grows bored with her boytoy.
“If that happens, she’s going to break Harry’s heart!”
Styles might need to prepare for heartbreak. A source previously told OK! in late April that Styles and Wilde's lust phase might be ending and "they're starting to realize that they don't have much in common, and a lot of it's because of their age gap." They also "like different music and food, and their style is opposite too."
Beyond that, they're both busy — Styles is occupied working on a new movie and Wilde "spends a lot of her time with her kids," explains a source.
