Eva Mendes EMENDES120707_03.jpg Has The Fast And The Furious' Eva Mendes been trying to slow things down?

TMZ is reporting that the PETA diva has been receiving treatment for substance abuse - for the last few weeks!

Eva's treatment is taking place at the Cirque Lodge in Utah, where Lindsay Lohan's made her most recent (and mostly successful) attempt at rehabilitation.

The starlet's rep spoke to PageSix.com earlier today, telling them "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."

Think this'll affect Eva's status as the Campari spokeswoman?
