My friend has a crush on my boyfriend, advice?

My best friend has a massive crush on my boyfriend. She clings onto his arm and teases him constantly. She's my friend but how do I politely tell her to back off?

It's getting really bad. She treats him as if it were her boy. Worst of all, its not only ruining mine and hers friendship but also ruining mine and my boyfriends relationship. She knows me and him and dating and she really needs to back down XD
