There are reports that Eva Mendes has already left rehab. She probably checked out when she heard Kirsten Dunst checked in.
According to Life & Style, Eva Mendes left Utah last night and took a fight to Los Angeles around 9pm.
Even though we found out that Eva was in rehab last week it doesn't mean that she pulled a Britney and spent only a week there. She was actually there several weeks before the public found out.
Her spokesperson released a statement when news of her rehab became public saying: "Eva has been working hard for the past year and made a positive decision to take some much needed time off to attend to some personal issues that, while not critical, she felt deserved some outside professional support."
The way her spokesperson put it, it sounds like Eva was on vacation.
