BOGOTA: Shakira’s son has taught her to simplify.  The 37-year-old singer - who has 15-month-old Milan with partner Gerard Pique - says the little boy’s need for her attention mean she has had to be more focused in her work so she has more free time to be with him. She said: ‘’Well I think he’s taught me, in general, he’s taught me how to simplify because he requires me most of the time. So I have to kind of learn how to be a little more direct with my own work, with the way I tackle my work.–EX
