House star Lisa Edelstein has praised her co-stars Jesse Spencer and Jennifer Morrison for their professionalism.

The couple announced that they had called off their wedding last week, but Edelstein - who plays Lisa Cuddy on the Fox drama - has insisted that any awkwardness between Jesse and Jennifer will not affect their work on the show.

''Jennifer and Jesse are consummate professionals,'' Lisa told People magazine. "They really have never brought their relationship onto the set to begin with, so they're not bringing their breakup onto the set either.

"I don't even know if they're actually broken up or they're just not getting married as planned. They're beautiful people, and they're good friends, and I really think that it's all going to be okay."
