Lea Michele [1] and Robert Buckley have already called time on their short-lived romance [2]. Us Weekly reveals that the two stars, who first began dating in May [3], reportedly split because they realized they were "better off as friends" and because of their busy schedules. Lea and Robert, who still managed to post a few sweet glimpses into their romance [4] on Instagram, won't be apart for long, though. They are currently filming Dimension 404, an upcoming science-fiction drama set to air on Hulu. The two are just the latest celebrity couple to call it quits [5] so far this year.
