Guess who's coming to dinner on This Is Us? It has to be somebody super important, Jack Pearson (Milo Ventimiglia) is breaking out his sport coat for the occasion.
"You sure are getting dressed up for this dinner," Rebecca (Mandy Moore) says in the exclusive This Is Us sneak peek above. "I don't think I've ever seen you wear a sports coat on the weekend."
"What are you talking about? I always wear a sports coat," Jack says.
And this gets a very telling "OK" from Rebecca. That "OK" comes with more.
