hanger-on
Someone who spends time with a person or a group of people hoping to benefit in some way from the association. The term implies that such a person is sycophantic or unwanted. Ever since Jennifer became a famous actress, she's surrounded by hangers-on trying to use her to further their own careers. Naturally, when she lost her fame and fortune, all those hangers-on deserted her. I'd be wary of these new friends of yours. Fame attracts many a hanger-on, you know.
