Selena Gomez loves a certain Taylor Swift song. The star has revealed that she thinks "Wildest Dreams" is the best song by her longtime BFF. "I think this is one of her, if not, I mean I guess I shouldn't say this, but I do think it's one of her best songs," Gomez explained while guest-hosting a music takeover. "It's incredibly well done. The lyrics, everything. Just the melodies—it's one of my favorites that no matter when it comes on, I will just blast it in any mood I'm in."
