Jennifer Lopez is refusing to find a new nanny to look after her baby twins, because she wants to be a full-time mom.

The nanny Lopez and husband Marc Anthony hired to look after three-month-old twins Max and Emme left the job last month, and, instead of replacing her, Lopez is caring for the pair around the clock.

A friend tells Us Weekly, "She's beyond hands-on."

And both Lopez and Anthony plan to put family first and their careers second for at least the next 12 months: "They both told their managers that the next year would be all about family."

Meanwhile, Anthony will take his wife and twins with him when he tours Spain next month.
