A source close to the situation explained:
The actress recently appeared on Ellen and talked about their picture perfect friendship as well as their exclusive get-togethers known as the Lonely Girls Club!
Basically, Selenita and her gal pals get together to talk about the single life while T-Swift provides the baked goods!
Um, where can we sign up?!! LOLz!
Ch-ch-check out the rest of the interview (above)!
If that's not enough scientific evidence to prove that they have the best friendship ever, she also reveals that the two met at a Jonas Brothers concert!
Seriously, Selena. Stop it before our heads explode with excitement!
