Miley Cyrus hat jeans smiles sunglasses Miley Cyrus hat jeans smiles sunglasses

Yesterday we spotted Miley Cyrus grabbing a coffee and running errands, and it appears as though the caffeine put the 17-year-old starlet in a much better mood -- when we snapped her leaving the gym earlier in the day, she was looking a bit bummed! Thank goodness for Starbucks!

On a different note, we love that Miley's been rocking her own hair lately, but we were blown away when we learned the starlet paid $24,000 for the weave that she was rocking when she promoted her new album, Can't Be Tamed earlier this month. Miley had the extensions shipped from Italy to New York to hairstylist Kristina Barricelli, and a source tells In Touch Weekly, "Miley bought the best hair possible, and then had it dyed to match hers exactly. Her hair is an investment."

It certainly is!
