Former Dexter actress Julie Benz is officially off the market!

The 40-year-old actress -- who most recently appeared on TV's A Gifted Man -- swapped vows with her marketing executive beau of four years, Rich Orosco, on Saturday, Us Weekly can confirm.

Accepting Orosco's proposal -- and an $80,000, 3-carat Kwiat engagement ring -- in June 2011, Benz was treated to a "pop-up Mexican fiesta" to celebrate her engagement.

"I can't believe that none of my friends leaked the surprise," Benz told Us after Orosoco arranged for nearly 60 of their closest friends and family to meet at their home, along with a Mariachi band. "It was like a Navy Seal operation."

This is Benz's second trip down aisle. She was married to actor John Kassir from 1998-2007.
