Of course the actor whose character makes fun of the reality star's family in the hit drama responds to her tweet.
"I'm starting to watch 'This Is Us.' Who watches it? Is it good?" Kardashian tweeted late Wednesday night.
"I watch it. I think it's worth a look," Hartley responded Thursday. "If it were me, I would watch it from the beginning. A good time to start if you ask me. Not too [far] along in the series, yet enough episode to binge if you feel."
"You'll laugh, you'll cry," he added.
Hartley's response gave us an extra laugh because his character, Kevin Pearson, actually referenced the reality star's family in the Season 2 premiere.
"The Kardashians aren't going anywhere. They're like gremlins," Kevin told his girlfriend after missing her once in a lifetime opportunity to meet one of them. "By next week, there'll be like, a bazillion more of 'em."
The joke couldn't have had better timing since the news of Khloe Kardashian's pregnancy broke earlier in the day, just four days after reports of younger half-sister Kylie Jenner's pregnancy began circulating.
"Watching 'Stranger Things' Season 1, Episode 4. I feel like I'm gonna be up all night trying to watch it all," Kardashian tweeted.
"YAY! So glad you're watching AND you have a whole new season to enjoy too! Hope you enjoy as much as I love 'KUWTK.' Bible. Okrrrrrr <3 (sic)," Brown responded.
