Some of the stars of "Modern Family" reunited to address one of the most pressing topics affecting families today: green text bubble discourse.

In a commercial for instant messaging platform WhatsApp, actors Ty Burrell, Julie Bowen, Eric Stonestreet and Jesse Tyler Ferguson seemingly reprised their roles from the beloved sitcom.

The ad shows Phil (Burrell), Claire (Bowen) and Cameron (Stonestreet) in a living room discussing a photo Haley (Sarah Hyland) sent. When Mitchell (Ferguson) asks to see the photo, Phil accidently slips that it's "in the group chat," sending everyone into an immediate panic.

"You started a family chat without me? Shame!" Mitch says.

Cameron assures him that it's not because of him but his new phone, with Claire citing "blurry photos" and "weird likes" that appear when Mitch sent a text to their old group chat.

The ad concludes with a house painter telling all four of them that they should communicate via WhatsApp so they can all access the same features.

A recent WhatsApp survey reported that 58% of Americans consider themselves "blue bubble" people. About 52% of survey respondents say they have a close friend or family member they don't speak to as regularly because device differences.

"Additional results also reveal bubble-based opinions that seem to widen existing gulfs, such as how some iPhone users see Android users as budget-conscious and in turn iPhone users are seen as status-conscious," the company said in a news release.
