Taylor Swift has allegedly penned five news songs about Harry Styles.
Despite the I Knew You Were Trouble hitmaker only splitting from the One Direction stud last week, the singer has already channelled her anger into brand new songs about her short-lived romance with the 18-year-old womaniser.
A source told The Sun newspaper: "Taylor writes music in the same way that other women chat to their friends on the phone. It's been how she deals with her emotions for most of her life.
"Harry and Taylor only dated for a short time but there were very strong feelings, so it's been a tough comedown."
The 23-year-old country starlet is famously open about her string of A-list exes - who include John Mayer, Taylor Lautner and Jake Gyllenhaal - in her lyrics, but refuses to reveal which of her former flames each song is about, with the exception of her candid hit Dear John.
She is said to be worried any new song she releases will be obviously linked to Harry, so has been careful to keep the tune more cryptic this time.
The insider added: "Lyrics have been written, but Taylor hasn't come close to deciding whether she'll ever release them. A song about it will surface at some point but it won't be anything like the way she had a dig at her other ex John Mayer in one of her other tracks."
Following her dramatic bust-up with Harry while holidaying together in the Caribbean, Taylor announced she was working on new material on Friday.
She tweeted: "Back in the studio. Uh oh... (sic)"
