The 24-year-old actor addressed the scandal in an interview with Good Day New York. Hoult and Lawrence were dating when the actress sent him nude photos of herself, and the pictures were later hacked and published online.
"It's shocking that things like that happen in the world," he declared. "It's a shame."
"I started to write an apology, but I don't have anything to say I'm sorry for," she asserted. "I was in a loving, healthy, great relationship for four years. It was long distance, and either your boyfriend is going to look at porn or he's going to look at you."
Hoult and Lawrence first began dating in 2011, but broke up in January 2013. The couple rekindled their relationship in July 2013 after filming X-Men: Days of Future Past, but split once more in August. The Hunger Games actress has since been linked to Coldplay frontman Chris Martin, and was photographed with the singer in late September.
Hoult will next appear alongside Chloe Grace Moretz, Charlize Theron and Christina Hendricks in Dark Places, while Lawrence is scheduled for The Hunger Games: Mockingjay - Part One in November.
