Harry Styles, Olivia Wilde Pack On The PDA During Romantic Vacation In Italy

It seems Harry Styles is certainly getting his "Watermelon Sugar" high this summer after apparent girlfriend Olivia Wilde flew down to meet the British pop star in Tuscany, Italy.

The good looking couple was spotted together on Wednesday, June 30, with their arms wrapped around each other while on a stroll. The loved-up photos were allegedly taken in the picturesque seaside town of Porto Ercole.

Since finishing up his latest project, Styles has been enjoying his time in Italy, as the former One Direction member was previously seen frolicking alone on Friday, June 25, ahead of Wilde's arrival.

"Harry has been seen taking a break on the beach in Porto Ercole after he finished filming My Policeman in London," a source dished, referring to the 27-year-old's role as a gay police officer who marries a woman while in a secret relationship with a man.

Meanwhile, Wilde — who was first linked to Styles in January after they met on the set of their upcoming psychological thriller, Don’t Worry Darling, which Wilde directed — joined her beau after spending time with 7-year-old son Otis and 4-year-old daughter Daisy, whom the 37-year-old shares with ex-fiancé Jason Sudeikis.

"Olivia has also been in London, spending time with her kids, who are there with Jason," the insider told Page Six. "Olivia stayed behind with her kids, then she flew into Porto Ercole to join Harry."

And while Sudeikis — who had a nine year relationship with Wilde before they called it quits last November — is hoping The Change Up actress' new flame is "just a phase," OK! exclusively learned that Wilde is planning on keeping Styles around, which Sudeikis needs to realize sooner rather than later, said the source.

"Olivia needs Jason to understand this is a serious relationship, whether he likes it or not," the OK! insider dished, noting that the brunette beauty "fell under [Harry's] spell." And now, "they're in that happy stage and enjoying themselves."

The Horrible Bosses actor, 45, is apparently "heartbroken" that his ex-fiancée moved on so quickly with the Grammy winner, however, he managed to find comfort in the arms of his Ted Lasso co-star Keeley Hazell.

In fact, Sudeikis turned towards Hazell when he first found out about his baby mama's new romance, with a source noting that the blonde bombshell "was brilliant and incredibly supportive" while Sudeikis was "understandably devastated."

While he and Hazell have been friends for years, OK! learned Sudeikis always found his co-star to be "incredibly attractive." The duo allegedly took their platonic relationship to the next level after he invited Hazell out for dinner one night with his mates in L.A.
