Katharine Mcphee's fling with Smash director Michael Morris is over, according to a U.S. report.

The pair hit headlines after they were snapped kissing in Los Angeles last month (Oct13), promoting speculation about the state of Morris' marriage to actress Mary MCCormack.

Singer/actress MCPhee, who is believed to have split from her actor/producer husband Nick Cokas earlier this year (13), is now said to have called time on her short-lived relationship with Morris.

A source tells People.com, "Katharine is no longer seeing Michael - at least for now."

Meanwhile, the status of star's own marriage to Cokas remains up in the air. The insider adds, "Katharine still has no plans to move forward with divorce at the moment, though they are not living together."
