The 21-year-old singer loves nothing more than hanging out with the Disney star, and their other friends, actress Emma Stone, 22, and Paramore frontwoman Hayley Williams, 21.
Taylor said: 'In my circle of friends I have Emma Stone, Selena Gomez ' she's like my little sister ' Hayley Williams and my best friend Abigail from high school. We all have crazy schedules but we make our time together count and laugh and have hilarious dinners. It's nice to have people I consider trustworthy, great friends.'
Thought Taylor is one of the US' biggest stars, she insists success hasn't changed her and all her old friends can still relate to situations in her life.
She added: I'd just give everyone around me a chance to understand what I'm going through. I tell my friends everything I'm feeling and they can relate to any situation I've been in.
'Maybe we haven't lived exactly the same life, but everybody has days when you're tired or frustrated.'
