Since the pandemic first hit, Pia and Patrick have been doing their relationship long-distance.
However in February, the couple were reunited in Sydney and Pia shared a gorgeous photo of her man posing with her sons Isaiah and Lennox.
With the Australian borders closed, Patrick, whose talent agency is worth approximately $480 million, had to obtain a special exemption to enter the country and completed the mandatory 14-day quarantine.
New Idea previously reported that Pia and Patrick secretly wed in May.
After the model and actress shared a photo of champagne bottles, candles and a gorgeous flower arrangement, captioning it "90 days", socialite Nina O'Brien, who is one of Pia's closest pals, seemed to confirm the news.
"Congratulations Mr. & Mrs. PPW 😘," she commented on the post.
According to the Herald Sun, Patrick was also spotted donning a gold wedding band during dinner with his new wife while the couple were in Malibu.
