Miley Cyrus and Ashley Tisdale wear BFF rings. We've all heard about 'purity rings', but you may wonder what a 'bff ring' is. Well, it's a piece of jewelry that two people wear to show that they're "best friends forever."



"Miley saw this Hidalgo ring and said to her mom, 'OMG, I need to get one of these for Ashley,'" a source told OK!. "She asked to order two - one for her and Ashley because they both collect things with horseshoes on them."

"They're really close, and this is their little way to say 'hi.' With their crazy schedules, it's how they stay connected."
