This very well connected source also said that our girl Miley felt like it was time to focus on her career.
"She wants to focus on her career. It wasn’t an easy decision, but this is ultimately what she wants.”
Despite the split, Kaitlynn and Miley (who were pals while they were married) are still tight.
"They’re still friends," the source told PEOPLE.
"They’ve been friends forever and were there for each other when they were both getting separated, but they’re just not in a romantic relationship anymore."
Miley and Kaitlynn first let the world know they were a couple a mere matter of days after Liam Hemsworth and Miley announced their separation.
The official separation statement was released to PEOPLE on August 10 and read: "Liam and Miley have agreed to separate at this time. Ever-evolving, changing as partners and individuals, they have decided this is what’s best while they both focus on themselves and careers.
"They still remain dedicated parents to all of their animals they share while lovingly taking this time apart. Please respect their process and privacy."
