Happy Endings Exclusive: Sunny Mary Elizabeth Ellis Makes [Spoiler] Pregnant!

Someone on Happy Endings will be announcing a pregnancy this spring — and she’ll have Mary Elizabeth Ellis to thank for the (pretend!) bun in the oven.

TVLine has learned exclusively that the It’s Always Sunny in Philadelphia waitress has booked a guest-starring role on the ABC comedy as Anna, a childhood friend of Jane and Alex’s who comes for a visit and immediately rubs Penny — whom she also knew back in the day — the wrong way by being really, really, really (wait for it) nice.

In fact, Anna is so persistently friendly and oppressively helpful that she sets in motion a chain of events that leads one of the gals to fake a pregnancy just to (unsuccessfully) ditch the super-clingy pal.

In addition to her time in Philadelphia, Ellis recently has appeared on Fox’s New Girl as Nick’s ex. Fun fact: She also represents the third alum of NBC’s short-lived Perfect Couples to guest on Happy Endings, following David Walton and Hayes MacArthur.
