Harry Styles and Emily Ratajkowski's alleged fling has reportedly left Olivia Wilde feeling blindsided and distressed, as whispers of a past threesome involving the three celebrities emerge. Insiders say that Wilde is now struggling to cope with the rumors and disappointment in Styles' behavior.

"Olivia is trying to navigate through another romantic drama in her life, and now she's confronted with rumors of being part of a throuple back then," shares a source close to the situation. "While she's denying it, what she can't shake is that Harry's making her look ridiculous — she's saying he's a real pig for putting her through this!"

Wilde, who had previously ended her engagement with 47-year-old Jason Sudeikis, was romantically involved with her "Don't Worry, Darling" co-star before parting ways with Styles in November after two years together. At the time, Styles reportedly claimed he needed a break to "find himself." Yet, the former One Direction singer was recently spotted with Ratajkowski in Tokyo, where he is currently touring.

"Olivia was entirely caught off guard when those cringeworthy photos surfaced online, particularly since she and Emily were together at an Oscars party just a few weeks prior," reveals the insider.

The rumors surrounding the supposed throuple have only added to the 39-year-old actress's embarrassment, with sources stating that those close to her, including Sudeikis, are now saying "I told you so" about Styles. This, in turn, only serves to further wound Wilde.

As the situation continues to unfold, Wilde remains focused on her career and personal life, while grappling with the impact of the rumors and Styles' alleged indiscretions.
