Momager is a mother who manages the career of one or more of her children; a manager who performs the duties of a mother.

妈咪经纪人指负责管理自己孩子事业的妈妈，或者履行一些妈妈职责的经纪人。

For example:

Kris Jenner is owning her reputation as a momager -- literally.

克里斯·金娜真的是名副其实的妈咪经纪人。

The Keeping Up with the Kardashians matriarch has just filed legal documents to trademark the word "momager" and embracing a nickname that has stuck ever since her family's rise to fame.

这位《与卡戴珊一家同行》节目的大家长已经正式为momager一词申请注册商标，这个从她们一家成名以来一直与她们同在的称呼终于被她们接受了。
