Those close to Selena Gomez were shocked when the Disney star had to be hospitalized because she felt exhausted and malnourished, and now sources reveal her mother, Mandy Teefey, is stepping in to make sure she slows down her intense schedule.

"Her schedule is insane," a Selena insider tells me. "She is one of the hardest working people in show business but now even Selena knows she needs to slow down. You have no idea how much work goes into promoting a record or a film."
