Rex Features
The actress, who is best known for her roles in 2 Fast 2 Furious and Hitch, has been receiving treatment at the Cirque Lodge clinic for several weeks.
A statement released by Mendes' representative explained: "Eva has been working hard for the past year and made a positive decision to take some much-needed time off to proactively attend to some personal issues that, while not critical, she felt deserved some outside professional support.
"Out of respect for Eva's privacy, we do not wish to discuss further details."
The statement was released following reports that Mendes had decided to seek help for a substance abuse problem.
