Songstress Taylor Swift has revealed that being made fun of during her days as a student has influenced how she processes new friendships and when she first became buddies with 'Girls' actress and writer Lena Dunham, she wondered if the star was mocking her. 

During a new interview with David Letterman (pictured left with Swift), the 'Shake It Off' beauty confessed that when she first noticed Dunham had been quoting her songs she thought she was poking fun at her as she was used to being teased at school:

"I Googled her and I saw her quoting my lyrics and I thought, she has to be doing that ironically, she has to be making fun of me... I have this big loser complex from school. Then we met in person...and we've been best friends ever since."
