Chrissy Metz, Justin Hartley, and Sterling K. Brown weren’t the only This Is Us stars who came out to celebrate The Big Three’s birthday on Twitter!
Sterling K. Brown’s real-life kids were on hand to help celebrate (and blow out the candle), while Justin Hartley shared that his birthday wish for The Big Three is for Kevin and Randall to figure out their differences.
Metz fittingly opened the video with a performance of “Happy Birthday,” with more stars chiming in with their own versions.
The actors who play the teen and young versions of Kate, Kevin, and Randall had their cakes and candles ready to celebrate as well.
