In Touch can exclusively reveal that newly single Eva Longoria has been going incognito on dates with hunky New York Jets quarterback Mark Sanchez.

“It looks like they’re testing the waters,” an insider tells In Touch, after Eva was spotted on June 4 shopping with 25-year-old Mark at a Kings supermarket in Bedminster, N.J. — where the football star has a home.

The next evening, Eva donned a blond wig as she and Mark had dinner and drinks with a group of friends at New York’s Hotel Griffou, where they looked very comfortable with each other, an insider tells In Touch: “They were laughing and having a great time.”

Eva and Mark — who was most recently linked to Sports Illustrated model Kate Upton — kept things hot on an island-hopping adventure in the Caribbean just weeks later.

Eva’s rep recently confirmed her split from Spanish singer Eduardo Cruz, whom she began dating in 2011.
