It's splitsville for "Star Trek" hunk Zachary Quinto and boyfriend Jonathan Groff.
"Zach being away and filming was not easy on them," US Weekly quotes a source as saying. "Now he's going to be in New York with his new Broadway play 'The Glass Menagerie.' They really loved each other, so it wasn't an easy split."
Meanwhile, Perez Hilton cites a source who claims the split was far from amiable, noting that things did "not end well" for the Hollywood pair.
Groff, a Broadway veteran known for his role on TV's "Boss" opposite Kelsey Grammar as well as guest-starring stints on "Glee," is currently gearing up to star in an as-yet-untitled HBO series which he recently described as focusing on "the gay experience." He'll also be seen opposite Julia Roberts and Mark Ruffalo in the film version of Larry Kramer's "The Normal Heart," which is set to air on HBO next year.
Groff is also said to be consoling "Glee" co-star Lea Michele, whom he befriended during the run of Broadway's "Spring Awakening," on the death of her boyfriend Cory Monteith, according to US Weekly.
In September 2012, Quinto confirmed he and Groff were in a relationship, but did not elaborate further.
"I'm incredibly happy, I'm incredibly lucky," Quinto told Out Magazine at the time.
