Taylor Swift always runs everything she does past Emma Stone, Selena Gomez and Dianna Agron.

The 22-year-old singer loves being ''so close'' to the trio - as well as her stylist friend Ashley and jewellery designer Clare - and she enjoys how they are always there for her when she wants complain about something or celebrate her success.

She said: ''My friends mean so much to me because they give me the opportunity to vent and complain about whatever I'm going through.

''They are also the people I want to celebrate with when things are going well. My best friends are Ashley, who is a stylist, Clare, who works for a jewellery designer, and Emma, Selena and Dianna, who are actresses.

''We are just so close and I need to talk to them before and after everything that happens to me.''

The 'Red' hitmaker - who is currently dating One Direction singer Harry Styles - admits she would question someone's trust if they started bragging about being friends with her, which would ultimately lead her to stop talking to them.

She added to Britain's Cosmopolitan magazine: ''My system with friends is I pretty much trust anyone until they give me a reason not to, and then I don't talk to them anymore.

''If someone shows they are lacking in character, spreading rumours or senselessly bragging about being friends with you, that's a reason to wonder if you can trust them.''
