The actor, who played Ross, Aniston's love interest in the show, helped welcome her to Instagram by dropping a Central Perk reference.
"Hi Jen! x," he captioned a photo of two LEGOS based on their characters, Ross and Rachel.
They're seen sitting in the famous coffee shop playing a piano.
Within minutes, Schwimmer's post gained 100k likes and it continues to grow.
Before his dedication post to Jen, the actor had only shared two photos.
One of the "Friends" cast on their 25th anniversary and a surveillance video of a Schwimmer look-alike stealing from a grocery store.
As The Blast reported, Aniston broke the Internet on Tuesday after joining the social media giant following months of being trolled by her former castmates.
Aniston got her revenge in the end because she trolled Courteney Cox, Matt LeBlanc and Reese Witherspoon right back with the first chance she got.
She's already befriended an ex-husband on Instagram too. No, not Brad Pitt.
The actress and her second ex-husband, Justin Theroux, started following each other, and he was even the first to comment on her very first post.
Aniston and Theroux were married from 2015-2017.
FYI -- if you're looking for the "Friends" cast LEGOS, they will set you back a pretty penny.
The whole set including all five iconic characters and the Central Perk set retail at $60.
The toy giant rolled them out just in time for the show's 25th anniversary.
