People: A second chance at love didn't work.
No reason was revealed for their second breakup. The funny duo dated for five years before they called it quits last July. But they rekindled their relationship just a few months later. "They're taking it slow," a source told PEOPLE last fall. "They're on the road back to being together."
The pair even managed to poke fun of their first split on Jimmy Kimmel Live! last October when she was a guest and they exchanged awkward silences and quips like, "Did you make sweet love to anyone while we were apart?"
