Update (9/27 at 10:45am): So it turns out all the mystery surrounding a possible Will & Grace reunion was actually a modern-day mini episode in support of Democratic presidential candidate Hillary Clinton. The cast premiered the 10-minute video ahead of last night's debate between Clinton and Donald Trump. 

The reunion is a bit of a let down after all those teasers, but at least they all look great!

Original Story (9/26 at 3:15pm): It's been 10 years since the series finale of Will & Grace, and the popular sitcom's cast has been hinting at a secret project all weekend. But what could it possibly be? A reunion special? Or maybe even a new season on Netflix, like the Gilmore Girls reboot? Whatever the actors are planning, they have definitely caused a ruckus on social media.

Debra Messing, Eric McCormack, Megan Mullally and Sean Hayes fueled the reunion rumors with an action movie-inspired teaser. It's only 20 seconds long, but look closely and you'll see the highlighted red words spell out this exciting phrase: "Will & Grace is back." The clip states "Only they can bring america back from the brink!" so let's hope this isn't a political spin.

Along with the teaser, the cast has been posting adorable photos of themselves on set as well as a group shot that's filled with smiles and barely any wrinkles. The foursome has not aged one bit:

Based on Messing's tweet, its possible for the cast to share more details of what exactly they have up their sleeve today. The Emmy award-winning Will & Grace ran on NBC from September 21, 1998-May 18, 2006, and was noted for its support of the LGBT community.
