Los Angeles: Actress Lea Michele has reportedly called it quits with her boyfriend Robert Buckley after dating for around two months. The split, however, was amicable, according to a source. "(They) just found they were better off as friends and wanted to support each other's careers," a source told usmagazine.com, adding that the former couple's busy schedules were partially to blame for the breakup. Michele's romance with Buckley may be over, but their professional relationship isn't. They are co-stars on the upcoming sci-fi drama "Dimension 404". They first sparked dating rumours in May after they were spotted on a dinner date in Santa Monica. Prior to her relationship with Buckley, Michele dated model-actor Matthew Paetz for two years.
