I don't think she's jealous -if so it's not to a point where she's angry with you. She's probably just sad because she's been trying so hard -for what seems like a fairly decent time now- to be a good singer. Having a best friend who is a good singer and is acknowledged for it might just be hard for her right now.
*Try talking to her -don't ask her if she's jealous, ask her if she's okay.
*Point out things she's good at -not randomly though... if it comes up in the moment. Ex: She's creative and good at making crafts. Compliment her. "Oh, that's really cute. Seriously!? How do you make these things?"
*Do something fun with her -let her know that's she amazing just the way she is.
I really hope this helps! ^-^

Well I don't think I can ask her because I can't really say "Hey are you jealous because I can sing better than you?" That would just make her plain mad at me, she does seem disappointed, if I don't walk up to her and start talking to her she would probably act like I'm not even there!
