Olivia Wilde will do anything to be with Harry Styles. She will even reportedly try to "move mountains" to spend time with her boyfriend.

This is the latest allegation from an insider who spoke with Life & Style for its February 14 issue. As claimed, the two celebrities are facing challenges in their relationship these days due to distance and schedule.

Styles and Wilde's respective busy days have reportedly taken a toll on their romance. It is said that for the couple, distance does not make the heart grow fonder.

Although the "In Time" actress has always ensured to be present at her partner's shows and performances, doing the same will be "a lot harder to pull off" soon as the "Dunkirk" star is about to embark on a tour.

Harry Styles will start his Europe shows in June. As reported, he will perform and make appearances across 32 cities, leaving Olivia Wilde behind.

The same source asserted that things will be "tough" for the actress because "in her heart," she wants them to be together at all times. While she has done a lot of things for this to happen in the past, "she cannot always be the one making concessions."

In the end, it is alleged that "work and family obligations" are pulling the two celebrities apart.

No one can confirm whether the claims are true. The informant failed to provide enough proof to support the story.

In addition, the celebrity couple has not made any remark about the matter, making the whole narrative questionable. So, unless Wilde and Styles break their silence and share that they are, indeed, having relationship problems, the latest story about them will remain as a mere rumor.

Meanwhile, witnesses recently spotted the two personalities at the Royal Academy of Arts. Elle said they were there for the "Francis Bacon: Man and Beast" exhibition on Thursday.

Harry Styles turned 28 years old on February 1, thus, causing reports to assume that the outing with his girlfriend was part of his birthday celebration.

A source who reportedly saw the couple in person, later on, told the Daily Mail that the two celebrities "looked like they were having lots of fun." They reportedly remained "undisturbed" during the museum date as only a few fans noticed their presence.

It was, also, pointed out that Olivia Wilde and Harry Styles did not hold hands in their outing. Even so, the closeness between them remained apparent "as they admired the art together."
