It all depends on the girl. If she is very shy and doesn't normally flirt with boys then I would talk to your friend about this. Never ever talk to the girl about this. It'll just make her want to flirt more with your friend. If she is very outgoing and flirts with any boy that will get his eyes on her then I wouldn't worry about it. That just means she's trying to get attention.
