The couple have split up, her rep confirms to PEOPLE.
"She’s doing fine," says the rep for the Ghost Whisperer star, 32, who dated actor-director Beh for less than a year.
Last November, the pair got cozy on the red carpet for the Rock the Kasbah gala in L.A., and Hewitt praised her new boyfriend as being an "old-fashioned" gentleman.
Hewitt is currently working on an episode of Hot in Cleveland.
