The couple - who had been together for two years - are said to have "grown apart".
According to In Touch magazine, via the Daily Mail, the 22-year-old actress and the Warm Bodies star have remained friends.
The pair met while filming X-Men: First Class in 2011. In an interview last November, Lawrence described Hoult as "her best friend".
"Hopefully I'm his best friend, too," she added. "He's my favourite person and makes me laugh harder than anybody."
Lawrence is nominated for a Golden Globe Award for her performance in Silver Linings Playbook opposite Bradley Cooper. She also received a 'Best Actress' Oscar nomination for the role yesterday (January 10).
