The ‘This Is Us’ Stars Have Something Major Up Their Sleeves for the Big Three’s Birthday

If you love This Is Us and surprises, then get ready because something big is coming.

Yesterday, This Is Us stars Mandy Moore (Rebecca), Sterling K. Brown (Randall) and Justin Hartley (Kevin) teased that the show is celebrating the Big Three’s birthday on August 31 with a little gift for fans. It’s not yet clear what that might entail, but the IRL Pearsons gave us a couple of vague hints on Instagram.

Moore, 35, kicked things off and posted a collage of photos featuring herself and Milo Ventimiglia, who plays Jack, as well as members of the Big Three, including Brown with his onscreen wife Susan Kelechi Watson (Beth).

“It may be the Big 3’s birthday, but the surprise is for you! Stay tuned…#ThisIsUs,” she wrote, adding a winky face and a party hat emoji. We love gifts, but we do wish we knew what it is. 

Brown shared a similar collage with himself and Watson at the forefront.

He wrote, “A big surprise is coming. 8/31 #ThisIsUs.”

Hartley posted another collage with a pic of himself, Brown and Chrissy Metz (Kate) sitting on a bench. He echoed his co-stars’ cryptic captions and gave us basically zero new information.
