Olivia Wilde expressed her gratitude for the birthday wishes she received in a March 21 Instagram post, noting that she "milked it for way too long and it's been great." The actress-director had just turned 39 and was likely looking to enjoy some positivity after a tumultuous year full of dramatic events, according to US magazine Life & Style.

Olivia has faced a series of challenges, including a messy custody battle with her former fiancé, Jason Sudeikis, and the recent emergence of a video showing her ex, Harry Styles, and her good friend, Emily Ratajkowski, kissing in Tokyo.

Court documents leaked on March 24 reportedly reveal that Olivia accused Jason of trying to "litigate her into debt" in their ongoing dispute over their two children, Otis and Daisy. Olivia's legal team allegedly stated, "While Jason can afford to spin his wheels with filing after filing, Olivia cannot," adding that she spends more than $100,000 per month outside of legal expenses.

They also claimed that "Jason seems intent on throwing whatever he can against the wall to see what will stick."

In light of these recent developments, Olivia has acknowledged that it has been a "difficult period." An insider shared that she has told friends, "This is the worst year of my life."

Despite the challenges, Olivia has tried to maintain a positive attitude. "Olivia prides herself on staying positive," says the insider, "no matter what life may throw her way."

However, the past year has tested her resilience. Olivia and Harry Styles' relationship began while they were working together on the film Don't Worry Darling, and she later had to deny rumors of an affair behind Jason's back. The insider notes that the negative publicity surrounding the film was not what Olivia had hoped for, and she felt "beat up by the embarrassing stories that kept coming out."

The situation has only been made more difficult by Harry's recent hookup with Emily Ratajkowski. The insider explains, "Olivia put so much into the relationship. Their November split was humiliating enough, but his hookup with Emily has left her reeling. Olivia's not sure how much more she can take."
