Jen Aniston may have just joined Instagram, but she's slaying the game already.
Our friends at Comments By Celebs were quick to discover the golden content.
Flagging several of Jen Aniston's responses, she's quickly making up for lost time.
Responding to LeBlanc's "Friends" 25th anniversary post from last month, in which he hashtagged her because she did not have an IG, Aniston wrote, "You don't have to # me anymore."
On a "rare night" photo that her real-life best friend Courteney Cox shared, Aniston made the adorable comment, "A rare comment and I love YOU."
"Friends" fans can't get enough, but her former castmates aren't the only celebrities Aniston is trolling.
Although Reese played her character's little sister on the iconic show, she and Aniston are gearing up to drop their highly-anticipated Apple series, "The Morning Show."
Commenting on a funny jab the "Big Little Lies" star took at Ellen DeGeneres, Aniston responded, "ummm....Reese? Is she still standing there?"
Sharing her first, and only, post so far, Aniston debuted a snap of all five "Friends" members.
"And now we're Instagram FRIENDS too. HI INSTAGRAM," she wrote.
Theroux followed it up by commenting, "Woot-Woot!! #first."
And that is how Jennifer Aniston broke Instagram!
