The box contains all the gifts given to Swift by her ex-boyfriends and they inspire her in writing songs on her relationship, reports thesun.co.uk.
"Taylor’s been working on a song about her split from Harry since they broke up. Her main source of material for the songs she’s written about her string of other famous ex-boyfriends comes from rooting around in a trunk where she hoards keepsakes of their relationships," a source said.
“Photos of Harry are now in there, along with a chain he had made for her when they got together last year which matches his own favourite necklace, of a paper plane. Trinkets like that should provide some easy material for her to build a song out of," the source added.
