See Mandy Moore's Sweet Birthday Tribute to 'One in a Million' Chris Sullivan

This Is Us actor Chris Sullivan (Toby) celebrated his birthday on July 19th, and his co-star Mandy Moore (Rebecca) posted the sweetest birthday tribute for him on Instagram. 

Moore's photo carousel includes several sweet moments that remind us why audiences felt so deeply connected to their This Is Us characters from the start. "You’re one in a million, @sullivangrams," Moore captioned the post. "Happy Bday, dear friend!! Can’t wait to have a breakfast burrito together soon!!"

Is it just us, or does Moore and Sullivan's breakfast burrito meetup sound like perfection?

Chrissy Metz (Kate) posted a birthday tribute to Sullivan via IG, as well. 

"Happy Birthday to one of the coolest, funniest, and most wonderful humans," wrote Metz in her post. "Wishing you a day and year full of health, happiness, and all of your heart's desires. 🎉🧁✨❤️ I miss you! @sullivangrams."

Susan Kelechi Watson (Beth) also swooped in to congratulate Sullivan on another successful trip around the sun.

"Hey it’s @sullivangrams birthday (#katoby4evaaaa)!! 😉🥳🎉 #thisisus," Watson wrote in her caption. 

Can we just take a moment to acknowledge how much we miss our weekly dose of the Pearsons? It's no secret that the This Is Us cast grew very close during their six-season run of the show. It's so heartwarming to know that even though the series is over, they still care about each other off-screen. 

It's easy to see why fans have been calling for another season of This Is Us—or, at the very least, a spin-off—but according to series creator Dan Fogelman, it's probably not going to happen.

“I’m pretty set on this being it,” Fogelman told TVLine. “Who knows what change of heart my ensuing midlife crisis brings, but I really feel we’ve put these stories to bed now.”

Watch This Is Us on Peacock and on NBC.
