Matthew Perry and Lizzy Caplan have proven that you can be a celebrity and keep your personal life private.
It has emerged that the two stars were dating for six years (like how did we miss that?!) but called time on their romance last year.

Matthew and Lizzy were dating for six years according to reports.
“It (the split) happened a year and a half ago. They haven’t been together for a long time,” a source told Us Weekly.
Rumours have it the relationship ended because the Friends star did not want to commit however neither him nor Lizzy, who you may recognise from Mean Girls, have commented on the news.

The actress has starred in New Girl, Mean Girls and The Bachelorette.
Not that we expect them to comment. They did after all, and rather impressively, keep their relationship a secret for six whole years!
