What are singing BFF’s good for??  Just ask Selena Gomez who helped her pal Taylor Swift wrap up her 98-show, 17-country tour this week.  Swift was performing her last show on Tuesday in New York City at the Madison Square Garden arena when Selena joined in on the fun.

The two singers belted out Selena’s “Who Says” together to the roaring crowd.  Oh did we mention Swift also had James Taylor help her end her tour in style.  Swift and Taylor performed two songs together. 

Check out Selena with her BFF Taylor.
