Miley has had a rough few months on the relationship front.
After Miley and Liam called it quits on their marriage - and their rollercoaster 10-year relationship - the star hooked up with Kaitlynn Carter.
Adding salt into the wound for Liam, the pair were linked just days after their split was announced.
The insider added, “She and Kaitlynn spent every day together and it just (wasn’t) anything that Miley wanted to continue doing. She wants to focus on her career.”
Miley caused concern last week when she posted photos of herself looking painfully thin.
The heartbreak of the last month seemed to have taken its toll on the former Disney star, as fans were shocked at to see Miley's frail arms and ribs on show in an Instagram post.
Miley - who was on holiday with her mother and sister in Arizona - took a photo at the famous caves in Antelope Canyon, dressed in a black sports bra and tiny denim shorts.
She captioned the photo with a Britney Spears lyric, writing: "But if you look at me closely ... you can see it in my eyes .... this girl will always find .... her way.....".
