Katharine McPhee and her boyfriend of two years, Elyes Gabel, have pulled the plug on their romance, according to multiple reports.

The couple actually split last month, Us Weekly claims. Rumors of a split began to make the rounds last week when she attended San Diego's Comic-Con for the "Scorpion" panel. Elyes, though, was noticeably absent.

"It's amicable and they remain friends," a source said told the magazine.

Kat and Elyes work together on the TV drama "Scorpion."

Just Jared also reported news of the split, saying, "They're still friends and work together almost every day. They still love each other but just couldn't make things work."

The two were first linked in August 2014 when they were spotted kissing in Los Angeles in between takes of their CBS series.

Katharine's love life has been pretty well-documented since she burst onto the pop culture as the runner-up on season 5 of "American Idol." She was previously married to entertainer Nick Cokas. However, they split shortly after she was photographed making out with her former "Smash" director, Michael Morris, who was married at the time. It was later reported that Katharine and Nick were on a break, but hadn't officially split up.

They tied to salvage their six-year marriage, but she eventually filed for divorce in May 2014. She began dating Elyes shortly afterward.

Neither has addressed the split on social media, although Elyes isn't super active on any of his social media accounts.

Kat put on a brave face and seemed happy last week while attending Comic-Con. She shared several images of her week to her Instagram page.
