Eva Mendes looked like she was auditioning for Betty Draper's role on "Mad Men" the way she dressed to hit up a Whole Foods store in Los Angeles recently.

She was all retro in a 1950s-style floral print skirt and knotted shirt. Hot.

But while the 38-year-old actress is still quite hot in the looks department, things may be cooling off for her on the relationship front. The Daily Mail reports that her pairing with Ryan Gosling has hit a snag.

"Ryan and Eva are having trouble seeing eye to eye," said a source. ‘He was having dinner with a blonde model who said she was from Berlin. He tried to disguise himself with a woolly hat and scarf and seemed eager not to be noticed as they sat at a beach table, but he was clearly entranced by her."

They'll both appear in "The Place Beyond The Pines," a thriller due out in theaters later this year, and there's speculation that the stars will announce that they've broken up before they start promoting it.

The producers mostly likely have their fingers crossed.
