Demi Moore and Mila Kunis are prepared to send up the fact that they have a "lot in common" (i.e, Ashton Kutcher), in the launch spot of a new celebrity-packed campaign from AT&T promoting its high-speed internet.

The push by the telecom giant, highlighting its new 2-gig and 5-gig fiber speeds, centers on the idea of ordinary people becoming so-called "gigillionaires" because of their high-speed internet. But that means celebrities might sometimes get eclipsed. 

In the first spot, Kunis and Moore are both attending a high school reunion. Both are expecting to win an award for Most Notable Alum (although playing it down in true celeb style). Not only are they shocked to spot each other on their way to the stage, but equally surprised when the award goes to Anna Gomez, an ordinary woman who's the school's "first gigillionaire." Moore and Kunis end up on stage with Moore muttering that she had no idea they went to the same high school and Kunis quipping that they "have a lot in common."

As a note to celebrity-watchers: Kunis and Moore really did both attend Fairfax High School, and it seems like they actually didn't know it until AT&T brought it to their attention, according to the brand's release. "It was during my first collaboration meeting with AT&T that we discovered Demi was also a Fairfax High alum," said Kunis in a statement. "I thought it would bring humor and laughs to what was already a great ad. I reached out to her and was so delighted she jumped on board. Now we’re just working on becoming gigillionaires." Moore added: "Who knew being a Fairfax alum would have brought this unexpected opportunity to come together with Mila in such a fun and playful way. AT&T has brought new depths to the importance of meaningful connection."

Another spot in the campaign features "Modern Family" star Sofia Vergara. In a similar storyline, she excitedly walks into a family gathering only to be outshone by a family member who now has AT&T Fiber. The spot will run in English and Spanish. A third spot will feature businesswoman Barbara Corcoran.

The ads, created via BBDO, will run in AT&T Fiber markets in more than 70 metro areas including L.A., San Francisco, Atlanta and Dallas in TV, digital, social, audio, and out-of-home.
