Perhaps singing about seeing other actresses’ boobs isn’t the best way to keep a relationship together, even if it did help this year’s Oscars become one of the most memorable airings of the award show in recent history.

E! news is reporting that Family Guy creator and Oscar host Seth MacFarlane has broken up with his girlfriend, Emilia Clarke.

The report’s unnamed source didn’t blame MacFarlane’s behavior, however. The split is supposedly due to the performers’ different work schedules, which left them on different continents. The source told E! that the couple “have remained friends.”

MacFarlane is working in the U.S. while Clarke is shooting the hit HBO TV show Game of Thrones in Europe. Clarke plays Daenerys Targaryen in the TV show, which is adapted from a series of popular fantasy novels authored by George R. R. Martin. MacFarlane is currently working on directing a movie called A Million Ways To Die in the West, which will star Amanda Seyfried, Liam Neeson, Sarah Silverman, and Charlize Theron.
