Kudos to Dean Sheremet!

The ex-husband of LeAnn Rimes graduated at the top of his class from Manhattan's French Culinary Institute on Tuesday, he tells exclusively.

To reach his feat, Sheremet, 29, completed six months (600 hours and 120 classes) of intense training.

"I won perfect attendance, graduating with distinction and highest cumulative score. Triple threat!" Sheremet gushed to Us Wednesday.

Given his status as valedictorian, the single guy was obligated to give a speech. "I dedicated the award to my classmates, who I learned just as much from as the program."

What's next for him? "I want to apprentice somewhere," he tells Us. "I would love to do a travel, food, lifestyle show someday."

Following Rimes' revealed affair with actor Eddie Cibrian, Sheremet and Rimes, 27, divorced in late December 2009 after six years together. In August 2009, he told Us that the breakup was "surreal. But I'm doing OK."
