Tony Barson/FilmMagicKatharine McPhee and Elyes Gabel have split up.
E! News can confirm the couple parted ways last month after two years together.
"It was an amicable split. They're still friends and work together almost everyday. They still love each other but just couldn't make things work," another source told Just Jared.
Meanwhile, Katharine, 32, and Elyes, 33, were first linked in 2014 after they were spotted stealing a kiss on the set of their show, Scorpion. They made things official shortly thereafter and were not afraid to show off their affection for one another, continuously smooching on set and sharing social media posts about each other.
The pair started dating amid the actress' divorce from her ex-husband, Nick Cokas, from who she filed for divorce in March 2014 after originally splitting a year before.
At the time, the actress's rep released the following statement to E! News: "After six years of marriage, and having been separated for the past year, Katharine McPhee has filed for a dissolution of marriage from Nick Cokas. The two have an amicable relationship and will remain friends. They ask that people respect their privacy during this time."
Katharine finalized her divorce in February of this year.
