Actress Eva Mendes is getting "professional support" for some "personal issues," her rep said Friday on the heels of a report saying she's in rehab battling a substance abuse problem.

"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," her rep told FOXNews.com.

"Out of respect for Eva's privacy, we do not wish to discuss further details," the rep added.

The "Ghost Rider" star, 33, has spent several weeks at Cirque Lodge in Utah, where Lindsay Lohan was recently treated, TMZ.com reported.

Mendes was just named "Sexiest Actress" of 2008 by Victoria's Secret, and Calvin Klein announced Friday that she will be featured in an upcoming Calvin Klein Fragrances advertising campaign, which will debut Fall 2008.
